Answer:
Hello!!! Princess Sakura here ^^
Explanation:
It is
because you should use
then just plug it in using
(1, 4) and (-2, -2).
![(4--2)/(1--2) =(6)/(3) =2](https://img.qammunity.org/2021/formulas/mathematics/high-school/lq1gn1io34fd5llrh64z8ew6ohixz04rw8.png)
That eliminates everything except the second one and the third.
So now we would find the b in the equation
![y=mx+b](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yj5waqmoy4i54laybzhhshd88hyo5w5rj5.png)
![y=mx+b\\4=2(1)+b\\4=2+b\\2=b\\b=2](https://img.qammunity.org/2021/formulas/mathematics/high-school/c34tqwh0hgqtmzhflkavmxva4zxrhi9z6q.png)
and that's all
