Question

Write an equation for each line.

Answer 1

Explanation:

1. orange line: y = 4

2. Green line:

(0, -1), (1, 0)

(0 + 1)/(1 - 0)= 1/1= 1

y + 1 = x - 0

y = x - 1

3. black line:

(0, 4), (2, 0)

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

y - 4 = -2(x - 0)

y - 4= -2x + 0

y = -2x + 4

4. blue line: x = -4
