Answer:
[tex]y=9x-13[/tex]
Step-by-step explanation:
Slope-intercept form is [tex]y=mx+b[/tex], where m is the slope, and b is the y-intercept. They tell us the slope is 9, so [tex]m=9[/tex]. They also tell us that the y-intercept is (0,-13), which means that [tex]b=-13[/tex]. Plugging both of those values in gives us the equation:
[tex]y=9x-13[/tex]
