Question

Write an equation in slope-intercept form of the line with the given characteristics:

1. Slope: -3; passes through (0,5),

2. Passes through (0, -2) and (4,-1)

Answer 1

Answer: -3x+5

1/4x - 2

Explanation:

Answer 2

1. y = -3x + 5

2. y = 1/4x - 2

Explanation:

y=mx+b

1. 5 = -3(0) + b, so b = 5

y = -3x + 5

2. (-2-(-1))/(0-4) = -1/-4 = 1/4

-2 = 1/4(0) + b, so b = -2

y = 1/4x - 2
