Find the x and y Intercepts y=-3x+8

$y = - 3 x + 8$

Step 1

Find the x-intercepts.

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

$0 = - 3 x + 8$

Solve the equation.

Rewrite the equation as $- 3 x + 8 = 0$ .

$- 3 x + 8 = 0$

Subtract $8$ from both sides of the equation.

$- 3 x = - 8$

Divide each term in $- 3 x = - 8$ by $- 3$ and simplify.

Divide each term in $- 3 x = - 8$ by $- 3$ .

$\frac{- 3 x}{- 3} = \frac{- 8}{- 3}$

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

$\frac{- 3 x}{- 3} = \frac{- 8}{- 3}$

Divide $x$ by $1$ .

$x = \frac{- 8}{- 3}$

Simplify the right side.

Dividing two negative values results in a positive value.

$x = \frac{8}{3}$

x-intercept(s) in point form.

x-intercept(s): $(\frac{8}{3}, 0)$

Step 2

Find the y-intercepts.

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

$y = - 3 \cdot 0 + 8$

Solve the equation.

Remove parentheses.

$y = - 3 \cdot 0 + 8$

Simplify $- 3 \cdot 0 + 8$ .

Multiply $- 3$ by $0$ .

$y = 0 + 8$

Add $0$ and $8$ .

$y = 8$

y-intercept(s) in point form.

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

Step 3

List the intersections.

x-intercept(s): $(\frac{8}{3}, 0)$

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