Write an equation of the line given the two points below (Write your equation in slope-intercept form, y=mx+b): (-1, -5) and (5, 5)

Answer 1

We need to find the slope m by finding rise over run, which is the difference in the y values over the differences in the x values.(-5 - 5)/(-1 - 5)

-10/-6

remember to reduce, now the slope m is 5/3

We need to find the y-intercept b.

Substitute one of the points and m into the y = mx + b. to solve for b.

5 = (5/3) 5 + b

5 = 25/3 + b

solve for b.

To write the equation, plug in 5/3 for m, and the solution for b into y = mx + b.
