Answer:
[tex]\boxed{y=\dfrac45x-1}[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex]
[tex]m=\dfrac{\text{rise}}{\text{run}}=\dfrac{\Delta y}{\Delta x}=\dfrac45[/tex]
[tex]y=\dfrac45x+b[/tex]
b is the y-intercept, which we can see from the graph is -1. Therefore, the equation is [tex]y=\dfrac45x-1[/tex]
