Question

Write the slope-intercept form of the line that

has a slope of −5, and passes through the
point (−4, 3).

Answer 1

y = -5x - 17

Explanation:

slope = m = -5

Use the point-slope form to find the y intercept, b: use point (-4, 3)

(y - 3) = -5(x - -4)

y - 3 = -5(x + 4)

y - 3 = -5x - 20

y = -5x -20 + 3

y = -5x - 17

double check the answer by plugging in (-4,3):

-5(-4) - 17 = 20 - 17 = 3 answer is correct
