Graph the linear equation. 3x−4y=12

show it on a graph

The graph is attached.

Step-by-step explanation:

By definition, the line intersects the y-axis when .

Then, in order to find the y-intercept, substitute into the equation and solve for "y":

By definition, the line intersects the x-axis when .

Then, in order to find the x-intercept, you can substitute into the equation and then you must solve for "x". Then you get:

Knowing that the line passes through the points and , you can graph it (The graph is attached).

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:
