Answer:vertex (-2,-12) and the equation y
=
2
x
^2
+
8
x
−
4
Step-by-step explanation:
U=-2. Subtract the 10 on both sides of the equal sign to get 4u=-8. After divide both sides by 4 to get “u=-4”
Answer:
Step-by-step explanation:
-3x + y = 15
y = 3x + 15. The slope here is 3. A parallel line will have the same slope.
y = mx + b
slope(m) = 3
(1,2)....x = 1 and y = 2
now we sub and find b, the y int
2 = 3(1) + b
2 = 3 + b
2 - 3 = b
-1 = b
so ur equation is : y = 3x - 1
