Find the x and y Intercepts x+2y=7

$x + 2 y = 7$

Find the x-intercepts.

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

$x + 2 (0) = 7$

Simplify $x + 2 (0)$ .

Multiply $2$ by $0$ .

$x + 0 = 7$

Add $x$ and $0$ .

$x = 7$

x-intercept(s) in point form.

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

Find the y-intercepts.

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

$(0) + 2 y = 7$

Solve the equation.

Add $0$ and $2 y$ .

$2 y = 7$

Divide each term in $2 y = 7$ by $2$ and simplify.

Divide each term in $2 y = 7$ by $2$ .

$\frac{2 y}{2} = \frac{7}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{7}{2}$

Divide $y$ by $1$ .

$y = \frac{7}{2}$

y-intercept(s) in point form.

y-intercept(s): $(0, \frac{7}{2})$

List the intersections.

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

y-intercept(s): $(0, \frac{7}{2})$
