We have the function
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](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dj7pifmrxtesbp01tsy3oo53ecwnnnjc04.png)
Now that we found that y-intercept =-3, any lineal function of the type:
will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type:
will have the same y-intercept. Where 'a' and 'b' can take all the real values.
