Question

A line passes through the point (8, -8) and has a slope of -5/2

Write an equation in slope-intercept form for this line.​

Answer 1

y=-5/2x+12

Explanation:

We know that the slope is -5/2 and the line passes through (8,-8). We can use the slope in the equation y=-5/2x+b and the given point to find for b. Plug in (8,-8) as x and y values to get -8=-5/2(8)+b. Multiply to get -8=-20+b, then add 20 to both sides to get 12=b. You can then use b to complete your equation, y=-5/2x+12.
