A great time to apply the quadratic formula
for a quadratic equation
Ax^2 + Bx +C =0
then
Answer:
-4
Step-by-step explanation:
Answer:B
Step-by-step explanation:
Answer:
y = -2x - 2
Explanation:
1. Find the slope (m) using the equation (y2-y1) / (x2-x1)
(y2-y1) / (x2-x1)
(-12 - 12) / (5 - -7)
(-24) / (12)
-2
2. To find “b”, plug in one of the points into the equation (e.g. if you choose the point (-7, 12), plug in -7 for x and 12 for y)
y = -2x + b
12 = -2(-7) + b
12 = 14 + b
-2 = b
3. Rewrite the equation using the information you have
y = -2x -2
