Answer:
y = 2x - 7
Explanation:
When x is equal to 0, then the y value is your y-intercept. So, your y-intercept is -7.
Now, pick two points. Let's pick (-1,-9) and (0,-7). We can add these into the slope formula.

Now, we can use the slope and the y-intercept and put them into a slope-intercept equation.
