Step-by-step explanation:

The up sloping line rises one unit for every one unit increase of x

m = Δy/Δx = 1/1 = 1

Its y intercept is (0, 5)

y = mx + b

y = 1x + 5

y = x + 5

The down sloping line drops six units for every four unit increase of x

m = Δy/Δx = -6/4 = -1.5

Its y intercept is (0, -5)

y = mx + b

y = -1.5x + (-5)

y = -1.5x - 5

we can verify the common intersection point by entering x = -4 into each equation

y = -4 + 5

y = 1

y = -1.5(-4) - 5

y = 6 - 5

y = 1

1/2
