Find the Parallel Line (-2,4) , y=-3x+10

$(- 2, 4)$ , $y = - 3 x + 10$

Use the slope-intercept form to find the slope.

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

$y = m x + b$

Using the slope-intercept form, the slope is $- 3$ .

$m = - 3$

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope $- 3$ and a given point $(- 2, 4)$ 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 $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$y - (4) = - 3 \cdot (x - (- 2))$

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

$y - 4 = - 3 \cdot (x + 2)$

Solve for $y$ .

Simplify $- 3 \cdot (x + 2)$ .

Rewrite.

$y - 4 = 0 + 0 - 3 \cdot (x + 2)$

Simplify by adding zeros.

$y - 4 = - 3 \cdot (x + 2)$

Apply the distributive property.

$y - 4 = - 3 x - 3 \cdot 2$

Multiply $- 3$ by $2$ .

$y - 4 = - 3 x - 6$

Move all terms not containing $y$ to the right side of the equation.

Add $4$ to both sides of the equation.

$y = - 3 x - 6 + 4$

Add $- 6$ and $4$ .

$y = - 3 x - 2$
