Answer: [tex]y=4x-9[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex]
I know b is -9 because there's where the line crosses the y intersection.
[tex]y=mx-9[/tex]
To find ''m'', we can use 2 different methods. I'm going to use one that follows a formula. First, locate two points in the graph.
[tex](0,-9);(3,3)[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ m=\frac{3-(-9)}{3-0}\\ m=\frac{3+9}{3}\\ m=\frac{12}{3}\\ m=4[/tex]
[tex]y=4x-9[/tex]
