Question

Use point-slope form to write the equation of a line that passes through the point

(-6,3) with slope – 2.

Answer 1

y = -2x - 9

Explanation:

Slope = - 2

Using the slope = -2 and the point (-6, 3) substitute into y= mx + b and solve for "b"

y = mx + b

3 = -2(-6) + b

3 = 12 + b

3 - 12 = b

-9 = b

The equation of the line is y = -2x - 9
