we are given x here, so we already know that our first coordinate is equal to -2.
in order to find the next coordinate, we have to substitute x for -2 in the y=mx+b equation.
the equation is
![y = (2)/(3) x + 23](https://img.qammunity.org/2023/formulas/mathematics/high-school/5rul8e3ew1sqxc1ra7dxcs5hgpymrfb4bn.png)
so in substituting x for -2 we get
![y = (2)/(3) ( - 2) + 23](https://img.qammunity.org/2023/formulas/mathematics/high-school/i3q3yoy2dzwpno7rtpuq4mc4g0hdl2oojd.png)
all we need to do is multiply ⅔ by -2, which gives us -1,3333.
we now have
![y = - 1.3333 + 3](https://img.qammunity.org/2023/formulas/mathematics/high-school/mnfar7xsx87ibhye5ckrdd4plwb2rshz9i.png)
so we add them together and get :
![y = 1.666666](https://img.qammunity.org/2023/formulas/mathematics/high-school/ucwt3wmip5rzvxffpcfatwey8wntfpbir3.png)
hope this helps!!<3
