Write in Slope-Intercept Form (7,0) and (-2,6)

$(7, 0)$ and $(- 2, 6)$

Find the slope of the line between $(7, 0)$ and $(- 2, 6)$ using $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ , which is the change of $y$ over the change of $x$ .

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.

$m = \frac{6 - (0)}{- 2 - (7)}$

Simplify.

Simplify the numerator.

Multiply $- 1$ by $0$ .

$m = \frac{6 + 0}{- 2 - (7)}$

Add $6$ and $0$ .

$m = \frac{6}{- 2 - (7)}$

Simplify the denominator.

Multiply $- 1$ by $7$ .

$m = \frac{6}{- 2 - 7}$

Subtract $7$ from $- 2$ .

$m = \frac{6}{- 9}$

Reduce the expression by cancelling the common factors.

Cancel the common factor of $6$ and $- 9$ .

Factor $3$ out of $6$ .

$m = \frac{3 (2)}{- 9}$

Cancel the common factors.

Factor $3$ out of $- 9$ .

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

Cancel the common factor.

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

Rewrite the expression.

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

Move the negative in front of the fraction.

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

Use the slope $- \frac{2}{3}$ and a given point $(7, 0)$ to substitute for $x_{1}$ and $y_{1}$ in the point-slope form $y - y_{1} = m (x - x_{1})$ , which is derived from the slope equation $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$y - (0) = - \frac{2}{3} \cdot (x - (7))$

Simplify the equation and keep it in point-slope form.

$y + 0 = - \frac{2}{3} \cdot (x - 7)$

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

Solve for $y$ .

Add $y$ and $0$ .

$y = - \frac{2}{3} \cdot (x - 7)$

Simplify $- \frac{2}{3} \cdot (x - 7)$ .

Apply the distributive property.

$y = - \frac{2}{3} x - \frac{2}{3} \cdot - 7$

Combine $x$ and $\frac{2}{3}$ .

$y = - \frac{x \cdot 2}{3} - \frac{2}{3} \cdot - 7$

Multiply $- \frac{2}{3} \cdot - 7$ .

Multiply $- 7$ by $- 1$ .

$y = - \frac{x \cdot 2}{3} + 7 (\frac{2}{3})$

Combine $7$ and $\frac{2}{3}$ .

$y = - \frac{x \cdot 2}{3} + \frac{7 \cdot 2}{3}$

Multiply $7$ by $2$ .

$y = - \frac{x \cdot 2}{3} + \frac{14}{3}$

Move $2$ to the left of $x$ .

$y = - \frac{2 x}{3} + \frac{14}{3}$

Reorder terms.

$y = - (\frac{2}{3} x) + \frac{14}{3}$

Remove parentheses.

$y = - \frac{2}{3} x + \frac{14}{3}$
