Slope is equal to the change in $y$ over the change in $x$ , or rise over run.

$m = \frac{change in y}{change in x}$

The change in $x$ is equal to the difference in x-coordinates (also called run), and the change in $y$ is equal to the difference in y-coordinates (also called rise).

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Substitute in the values of $x$ and $y$ into the equation to find the slope.

$m = \frac{0 - (3)}{2 - (0)}$

Substitute the value of $m$ into the slope-intercept form of the equation, $y = m x + b$ .

$y = (- \frac{3}{2}) \cdot x + b$

Substitute the value of $x$ into the slope-intercept form of the equation, $y = m x + b$ .

$y = (- \frac{3}{2}) \cdot (0) + b$

Substitute the value of $y$ into the slope-intercept form of the equation, $y = m x + b$ .

$3 = (- \frac{3}{2}) \cdot (0) + b$

Rewrite the equation as $(- \frac{3}{2}) \cdot (0) + b = 3$ .

$(- \frac{3}{2}) \cdot (0) + b = 3$

Simplify $(- \frac{3}{2}) \cdot (0) + b$ .

Multiply $0$ by $- 1$ .

$0 (\frac{3}{2}) + b = 3$

Multiply $0$ by $\frac{3}{2}$ .

$0 + b = 3$

Add $0$ and $b$ .

$b = 3$

The values of the slope and y-intercept are $m = - \frac{3}{2}$ and $b = 3$ .

$m = - \frac{3}{2}$

$b = 3$
