What is the value of m in the equation y=x^2+mx-9 with vertex (-1.5,-11.25)
1 answer:
3
Step-by-step explanation:
Step 1:
Let the given equation be
Step 2:
Applying the given vertices and simplifying we will get m
-11.25 = (-1.5)² +m(-1.5) -9
-1.5m = -11.25 + 9 - 2.25
= -4.5
m = (-4.5) / (-1.5)
= 3
