Step 1.1

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

$y = m x + b$

Step 1.2.2.1.1

Cancel the common factor.

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

Step 1.2.2.1.2

Divide $y$ by $1$ .

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

Step 1.3

Reorder terms.

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

Step 2

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

Step 2.1

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

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

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

Step 2.2

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