Which best describes the relationship between the lines with equations −9x+9y=1 and 7x+2y=4?

is it 35

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
