From the point-slope formula, we have:
where m is the slope, (x_0,y_0) are known points.
In this case, we have the slope and two points, we can substitute in the formula to get:
therefore, a=3
Note: you can also find a if you use the slope formula.
Answer:
-39
Step-by-step explanation:
a=-6 b=5 c=-2
a3-b+4c2
(-6)3-(5)+4(-2)2
