I need help with number 4 write an equation using y=Mx+b

We ant to find a linear function that has a x-intercept -2 and a y-intercept -2/3. Then, this function must contain the points (-2,0) and (0,-2/3).
For any line passing through two points (a,b) and (c,d), its slope is given by:
[tex]\text{slope}=\frac{d-b}{c-a}[/tex]Therefore, the slope M of the function we are trying to find is:
