Write the point-slope form of the equation of the line described. through: (2, -3), parallel to y = x + 5

y + 3 = -5(x + 2)
y + 3 = -3(x + 2)
y + 3 = x - 2
y -2 = x +3

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:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
