Find the Slope and y-intercept -7x+3y=15

$- 7 x + 3 y = 15$

Step 1

Rewrite in slope-intercept form.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Add $7 x$ to both sides of the equation.

$3 y = 15 + 7 x$

Divide each term in $3 y = 15 + 7 x$ by $3$ and simplify.

Divide each term in $3 y = 15 + 7 x$ by $3$ .

$\frac{3 y}{3} = \frac{15}{3} + \frac{7 x}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 y}{3} = \frac{15}{3} + \frac{7 x}{3}$

Divide $y$ by $1$ .

$y = \frac{15}{3} + \frac{7 x}{3}$

Simplify the right side.

Divide $15$ by $3$ .

$y = 5 + \frac{7 x}{3}$

Write in $y = m x + b$ form.

Reorder $5$ and $\frac{7 x}{3}$ .

$y = \frac{7 x}{3} + 5$

Reorder terms.

$y = \frac{7}{3} x + 5$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = \frac{7}{3}$

$b = 5$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $\frac{7}{3}$

y-intercept: $(0, 5)$

Slope: $\frac{7}{3}$

y-intercept: $(0, 5)$
