Question

A line passes through the point (-10, -8) and has a slope of -1/2. Write an equation in slope intercept form for this line

Answer 1

Start with the slope intercept formula.

y = mx + b

Plug in the slope and coordinates for x and y and solve for b (y-intercept)

-8 = -1/2(-10) + b
-8 = 5 + b
-13 = b

Then rewrite the equation in slope intercept form

y = -1/2 x - 13
