We have the function
y = (2)/(3) x -3 and we want to find a function that has the same y-intercept than the previous function.

First, let's find the y-intercept by subtituting 0 for 'x'.


y = (2)/(3) (0) -3 = -3

Now that we found that y-intercept =-3, any lineal function of the type:
y = ax - 3 will have the same y-intercept. Where 'a' can take all the real values.

Also, any quadratic function of the type:
y=ax^(2) + bx - 3 will have the same y-intercept. Where 'a' and 'b' can take all the real values.
