# find the equation of a line given that you know its slope and y-intercept

1. Find the slope and y-intercept of the straight-line 5x - 3y 15 0.We will learn how to solve different type of problems on slope and intercept from the given equation. Since you now have two points on the graph you can draw a line through these points and that is the graph you need. Again you can also find additional points by assuming values for x and solving for corresponding values of y. ThenWrite the equation of the line with given slope and y-intercept. Slope and finding the equation of a line.However, you must start with its correspond-ing x in the denominator. Slope-intercept form: The slope-intercept form of an equation with slope m and yintercept b is given by y mx b. Often in mathematics it is useful to be able to write the equation of a line, given its slope and any point on the line. In this section, we will derive a third special form for a line for this purpose.35. L has y intercept (0, 3) and is parallel to the line with equation y 3x 5. Because you now know both the slope and the y-intercept, you can use the slope-intercept form.Writing an equation of a line given its slope and a p o I n t. STEP 1 First find the y-intercept.

Substitute the slope m and the coordinates of the given point (x, y) into the The graph of a linear equation is a non-vertical line with slope m and y- intercept b.Example of Case 2: Find the linear equation whose graph has slope 3 and passes through the point (4, -3).Substitute that value into the partially determined equation given in () to obtain. y 3x - 15 as the 3.5 Finding Linear Equations. Learning Objectives. Given a graph, identify the slope and y-intercept.Finding the equation of a line can be accomplished in a number of ways, the first of which makes use of slope-intercept form, ymxb. Rewrite the given equation in slope intercept form and find its slope. 4y -4x 8. Divide both sides by 4 y -x 2 slope m2 -1.Another calculator to find slope, x and y intercepts given the equation of a line.Find Slope and Intercepts of a Line - Calculator. In this lesson you will learn how to find an equation for a line if you know its slope and a point on the line, or two points on the line.

Remember that this equation is in slope-intercept form, so 2 is the slope of the line and 1 indicates where the line crosses the y-axis. This is a vertical line with equation x 2, since all points have an x-value of 2. Example: Graph the line through the points (2,1), (0, 1), find its slope, and2.3 Graphing - Slope-Intercept Form Objective: Give the equation of a line with a known slope and y-intercept. When graphing a line we found What is the equation of the line in slope - intercept form for 2x5y5. Write the equation of the line passing through the given points. write the equation in standard form. In a poll 37 of the people polled answered yes to the question are you in favor of the death penalt. An example of a linear equation with three variables, x, y, and z, is given by: ax by cz d 0, where a, b, cAll its content applies for complex solutions and, more generally for linear equations with coefficients and solutions in any field.where m is the slope of the line and b is the y intercept In order to find the slope of a line that connects two points, you must find the change in the y-values over the change in the x-values.This is called the equation of a line, also known as an line written in " slope-intercept form." It tells us exactly how a line is positioned along the x and y axis as Steps to follow: Example: How to find the equation of a line that goes through the point (1, 3) and has a slope of 2. What we know from the problem: that the slope is 2 so we can write y 2x b Our goal: to find the y-intercept or "b". Graph this line by using its slope and y-intercept. -3x y 2. First things first, we need the equation in slope-intercept form.Find the equation of the line in slope-intercept form for the following graph. Show Answer Gimme a Hint. FINDING THE EQUATION OF A LINE WHEN THE SLOPE AND A POINT ARE KNOWN Because the slope is part of an equation, m yx---22---------yx---11 , we can substitute the slope and one of the points in. the equation to find the y-intercept equation (see section 3.2). First, we want to consider nding the equation of a line when its slope and y intercept are known. Suppose that the y intercept of a line is (0, b). Then the point at which the line crosses the y axis has coordinates (0, b). Look at the sketch at left. MAT 0028 ALEKS Module 4: Finding the slope and y-intercept of a line given its equation in the form axbyc Line is an endless line, which forms the shortest path between any of two its points.
