Answer:

Solve for x: x = 4 - 4y/3

Solve for y: y = 3 - 3x/4

X intercept(s): (4, 0)

Y intercept(s): (0, 3)

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
