Find the Slope and y-intercept 5x+2y=7

$5 x + 2 y = 7$

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.

$y = m x + b$

Subtract $5 x$ from both sides of the equation.

$2 y = 7 - 5 x$

Divide each term in $2 y = 7 - 5 x$ by $2$ and simplify.

Divide each term in $2 y = 7 - 5 x$ by $2$ .

$\frac{2 y}{2} = \frac{7}{2} + \frac{- 5 x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{7}{2} + \frac{- 5 x}{2}$

Divide $y$ by $1$ .

$y = \frac{7}{2} + \frac{- 5 x}{2}$

Simplify the right side.

Move the negative in front of the fraction.

$y = \frac{7}{2} - \frac{5 x}{2}$

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

Reorder $\frac{7}{2}$ and $- \frac{5 x}{2}$ .

$y = - \frac{5 x}{2} + \frac{7}{2}$

Reorder terms.

$y = - (\frac{5}{2} x) + \frac{7}{2}$

Remove parentheses.

$y = - \frac{5}{2} x + \frac{7}{2}$

Step 2

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

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

$m = - \frac{5}{2}$

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

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

Slope: $- \frac{5}{2}$

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

Slope: $- \frac{5}{2}$

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