Question

Need help with equation for all the lines

Answer 1

Brown: (2,0) and (0,4)

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

y-intercept, b = 4

Equation: y = -2x + 4

Green: (5,4) and (0,-1)

Slope = (4 + 1) / (5 - 0) = 1

y-intercept, b = -1

Equation: y = x - 1

Blue:

Equation: x = -4

Orange:

Equation: y = 4

Answer 2

Green: 4x-1

Blue: x = -4

Red: -2x+4

Orange: 0x+4
