Answer:
y = 2x - 7
Step-by-step 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.
[tex]Slope(m)=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-7-(-9)}{0-(-1)}[/tex]
[tex]m=\frac{2}{1}[/tex]
[tex]m=2[/tex]
Now, we can use the slope and the y-intercept and put them into a slope-intercept equation.
[tex]y=mx+b[/tex]
[tex]y=2x-7[/tex]
