Answer:
Step-by-step explanation:
Steps
1] On the right, put brackets around the 1st 2 terms.
y = (x^2 + 2x) - 6
2] Divide the second term's coefficient by 2 and square the result.
2/2 = 1
3] Square the result
1^2 = 1
4] Add that inside the brackets
y = (x^2 + 2x + 1) - 6
5] Subtract 1 outside the brackets. The original equation is still there.
y = (x^2 + 2x + 1) - 6 - 1
y = (x^2 + 2x + 1) - 7
6] What is inside the brackets is a perfect square.
y = (x + 1)^2 - 7
Answer D
Answer:
Step-by-step explanation:
(3,−1) (4,7)
Slope = y₂-y₁/x₂-x₁
= 7- [-1]/4-3
=7+1/1 = 8/1
= 8
m = 8 ; (4,7)
y-y₁= m(x-x₁)
y - 7 = 8 * (x - 4)
y -7 = 8x - 32
y = 8x - 32 + 7
y = 8x - 25
