Find the x and y Intercepts 7x-8y=112

$7 x - 8 y = 112$

Step 1

Find the x-intercepts.

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

$7 x - 8 \cdot 0 = 112$

Solve the equation.

Simplify $7 x - 8 \cdot 0$ .

Multiply $- 8$ by $0$ .

$7 x + 0 = 112$

Add $7 x$ and $0$ .

$7 x = 112$

Divide each term in $7 x = 112$ by $7$ and simplify.

Divide each term in $7 x = 112$ by $7$ .

$\frac{7 x}{7} = \frac{112}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 x}{7} = \frac{112}{7}$

Divide $x$ by $1$ .

$x = \frac{112}{7}$

Simplify the right side.

Divide $112$ by $7$ .

$x = 16$

x-intercept(s) in point form.

x-intercept(s): $(16, 0)$

Step 2

Find the y-intercepts.

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

$7 (0) - 8 y = 112$

Solve the equation.

Simplify $7 (0) - 8 y$ .

Multiply $7$ by $0$ .

$0 - 8 y = 112$

Subtract $8 y$ from $0$ .

$- 8 y = 112$

Divide each term in $- 8 y = 112$ by $- 8$ and simplify.

Divide each term in $- 8 y = 112$ by $- 8$ .

$\frac{- 8 y}{- 8} = \frac{112}{- 8}$

Simplify the left side.

Cancel the common factor of $- 8$ .

Cancel the common factor.

$\frac{- 8 y}{- 8} = \frac{112}{- 8}$

Divide $y$ by $1$ .

$y = \frac{112}{- 8}$

Simplify the right side.

Divide $112$ by $- 8$ .

$y = - 14$

y-intercept(s) in point form.

y-intercept(s): $(0, - 14)$

Step 3

List the intersections.

x-intercept(s): $(16, 0)$

y-intercept(s): $(0, - 14)$

Step 4

Find the x and y Intercepts 7x-8y=112
