Question

Find an equation for the line that passes through the points (-6,-3) and (2,-1)

Answer 1

y = 1/4x - 1 1/2

Explanation:

(-6, -3) (2,-1)

y = -3 - (-1) = -2 = 1

x = -6 - 2 = -8 = 4

y = mx + b

-1 = 1/4(2) + b

-1 = 1/2 + b

-1/2 -1/2

-1 1/2 = b

y = 1/4x - 1 1/2

The final equation is y equals one fourth x minus one and one half.
