Step-by-step explanation
A linear equation can be written in the following form:
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
where m is the slope and b the y-intercept.
As we are already given the slope, then we get the equation:
![y=-(3)/(2)x+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/hlblm608gzzz19508m4rjw0qmvaf0i9n94.png)
Replacing the point given we can calculate b:
![-2=-(3)/(2)(-8)+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/3nwvgxur23zx6v39di06zblr1u0s69b7jt.png)
![b=-2-12=-14](https://img.qammunity.org/2023/formulas/mathematics/high-school/skt0lh07bn4v5jmaie6p3mjzu5ag3htq0e.png)
Then the equation is:
![y=-(3)/(2)x-14](https://img.qammunity.org/2023/formulas/mathematics/high-school/9xlrq6pchevlju8sffkjzdb3zpr20wbpxk.png)
Then, we would have to get the form Ax+By=C , however, as we do not want fractions, we have to multiply the equation times two:
![2y=-3x-28](https://img.qammunity.org/2023/formulas/mathematics/high-school/nrgozziivtkdr9y86n07jw7ttxyp0lihj2.png)
Rearranging the function we get:
![3x+2y=-28](https://img.qammunity.org/2023/formulas/mathematics/high-school/hrq63hvhilwhrtcyp4t1yyb54w1gcns6lz.png)
