Question

3. Write the equation of the line with the given information. Give your answer in

the form y=mx+.
(a) the line has a slope of m=−2
7 and passes through the point (−14,8)
(b) the line passes through the points (−5,−10) and (10,14)

Answer 1

(a) y = 2x - 20

(b) y = 8/5x -2

Explanation:

a) point (-14,8). Slope: -2

y - 8 = -2(x - - 14)

y - 8 = -2x - 28

y = -2x -28 + 8

y = - 28x - 20

b) y - - 10 = 8/5 (x +5)

y + 10 = 8/5 +8

y = 8/5x +8-10

y = 8/5x - 2
