Find the x and y Intercepts 5x-4y=40

$5 x - 4 y = 40$

Step 1

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$5 x - 4 \cdot 0 = 40$

Solve the equation.

Simplify $5 x - 4 \cdot 0$ .

Multiply $- 4$ by $0$ .

$5 x + 0 = 40$

Add $5 x$ and $0$ .

$5 x = 40$

Divide each term in $5 x = 40$ by $5$ and simplify.

Divide each term in $5 x = 40$ by $5$ .

$\frac{5 x}{5} = \frac{40}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 x}{5} = \frac{40}{5}$

Divide $x$ by $1$ .

$x = \frac{40}{5}$

Simplify the right side.

Divide $40$ by $5$ .

$x = 8$

x-intercept(s) in point form.

x-intercept(s): $(8, 0)$

Step 2

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

$5 (0) - 4 y = 40$

Solve the equation.

Simplify $5 (0) - 4 y$ .

Multiply $5$ by $0$ .

$0 - 4 y = 40$

Subtract $4 y$ from $0$ .

$- 4 y = 40$

Divide each term in $- 4 y = 40$ by $- 4$ and simplify.

Divide each term in $- 4 y = 40$ by $- 4$ .

$\frac{- 4 y}{- 4} = \frac{40}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 y}{- 4} = \frac{40}{- 4}$

Divide $y$ by $1$ .

$y = \frac{40}{- 4}$

Simplify the right side.

Divide $40$ by $- 4$ .

$y = - 10$

y-intercept(s) in point form.

y-intercept(s): $(0, - 10)$

Step 3

List the intersections.

x-intercept(s): $(8, 0)$

y-intercept(s): $(0, - 10)$

Step 4

Find the x and y Intercepts 5x-4y=40
