Answer
$y = -7x + 10$
Work Step by Step
The easiest equation to work with, in this case, is the slope-intercept form.
Plug in the slope and $y$-intercept into the slope-intercept form, which is given by the following formula:
$y = mx + b$, where $m$ is the slope of the line and $b$ is the y-intercept.
In this exercise, the slope, $m$, is $-7$. The $y$-intercept, $b$, is $10$.
Thus, the equation is:
$$y = -7x + 10$$
