The equation for slope intercept is y=mx+b
M represents the slope of the equation while b represents the y-intercept.
Slope formula is y2-y1/x2-x1
The slope would be 2/3
Plug in the slope and the equation would be y=2/3x+b
Now you need to find the intercept, choose on of the coordinates and plug it into the equation. I chose (6,-1)
The final equation would be y=2/3x-5
