Find the x and y Intercepts 4x-7y=28

$4 x - 7 y = 28$

Step 1

Find the x-intercepts.

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

$4 x - 7 \cdot 0 = 28$

Solve the equation.

Simplify $4 x - 7 \cdot 0$ .

Multiply $- 7$ by $0$ .

$4 x + 0 = 28$

Add $4 x$ and $0$ .

$4 x = 28$

Divide each term in $4 x = 28$ by $4$ and simplify.

Divide each term in $4 x = 28$ by $4$ .

$\frac{4 x}{4} = \frac{28}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 x}{4} = \frac{28}{4}$

Divide $x$ by $1$ .

$x = \frac{28}{4}$

Simplify the right side.

Divide $28$ by $4$ .

$x = 7$

x-intercept(s) in point form.

x-intercept(s): $(7, 0)$

Step 2

Find the y-intercepts.

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

$4 (0) - 7 y = 28$

Solve the equation.

Simplify $4 (0) - 7 y$ .

Multiply $4$ by $0$ .

$0 - 7 y = 28$

Subtract $7 y$ from $0$ .

$- 7 y = 28$

Divide each term in $- 7 y = 28$ by $- 7$ and simplify.

Divide each term in $- 7 y = 28$ by $- 7$ .

$\frac{- 7 y}{- 7} = \frac{28}{- 7}$

Simplify the left side.

Cancel the common factor of $- 7$ .

Cancel the common factor.

$\frac{- 7 y}{- 7} = \frac{28}{- 7}$

Divide $y$ by $1$ .

$y = \frac{28}{- 7}$

Simplify the right side.

Divide $28$ by $- 7$ .

$y = - 4$

y-intercept(s) in point form.

y-intercept(s): $(0, - 4)$

Step 3

List the intersections.

x-intercept(s): $(7, 0)$

y-intercept(s): $(0, - 4)$

Step 4

Find the x and y Intercepts 4x-7y=28
