Answer:

x-intercept: (-6,0)

y-intercept: (0,-8)

Explanation:

The x-intercept is when y = 0.

The y-intercept is when x = 0.

Each intercept can be solved with substitution in the standard form equation.

Given the re-arranged standard form equation is

-3y = 4x + 24

With a standard form equation being in the form:

Ax + By = C.

-3y = 4x + 24 →

-3y – 24 = 4x + 24 – 24 →

-3y – 24 = 4x →

-3y + 3y – 24 = 4x + 3y →

-24 = 4x + 3y →

4x + 3y = -24

x-intercept:

given y = 0

4x + 3(0) = -24 →

4x = 24 →

4x / 4 = -24 / 4 →

x = -6 →

(-6, 0)

y-intercept:

given x = 0

4(0) + 3y = -24 →

3y = -24 →

3y / 3 = -24 / 3 →

y = -8 →

(0, -8)
