Web2) The Slope-Intercept Formula y = mx + b. As the names imply the form that you use is dependant on the information you are given to start with. Example 1: Find the equation of the line that has a slope of and contains the point (2, -1). 1 3 Solution . Since the information given is a point and the slope, the point slope formula is . used. WebSlope intercept form is written as y = m x + b Take the point slope form equation and multiply out 7 times x and 7 times 2. y - 5 = 7 (x - 2) y - 5 = 7x - 14 Continue to work the …
4.6 Find the Equation of a Line - OpenStax
WebMar 11, 2024 · To find the equations for lines, you need to find m and c. m is the slope. For example, if your line goes up two units in the y direction, for every three units across in the x direction, then m=2/3. If you have the slope, m, then all you need now is c. To find c in any line, you can use any (x,y) points you know. WebWrite the equation of the line given the slope and one point. 1.) y = 3x + b and (1, 4) 2.) y = -x + b and ( -3, 5) 3.) 3x + y = b and ( 4, -10) 4.) slope = 2, through (1, 5) ... Point Slope Form: Slope Intercept Form: Standard Form: Slope: Example 1: Find the slope of each of the given lines. Show all work. Slope of Line A: coffee shops eden prairie mn
