Answer:
A
Step-by-step explanation:
Given
y = x² + 2
Substitute the x value from an ordered pair from each table into the equation and compare the value obtained with the y value of the ordered pair
Table A
using (- 2, 6 )
y = (- 2)² + 2 = 4 + 2 = 6 ← this corresponds to the y value of the ordered pair
Table B
Using (- 2, - 2)
y = (- 2)² + 2 = 4 + 2 = 6 ≠ - 2 ← thus not a solution
Table C
Using (- 2, - 2)
y = (- 2)² + 2 = 4 + 2 = 6 ≠ - 2 ← thus not a solution
Thus Table A gives the solutions to y = x² + 2

Answer:
x=3 and y=3
Step-by-step explanation:
−x+8y=21for x:
−x+8y=21
−x+8y+−8y=21+−8y(Add -8y to both sides)
−x=−8y+21
−x
−1
=
−8y+21
−1
(Divide both sides by -1)
x=8y−21
Step: Substitute8y−21forxin−4x+2y=−6:
−4x+2y=−6
−4(8y−21)+2y=−6
−30y+84=−6(Simplify both sides of the equation)
−30y+84+−84=−6+−84(Add -84 to both sides)
−30y=−90
−30y
−30
=
−90
−30
(Divide both sides by -30)
y=3
Step: Substitute3foryinx=8y−21:
x=8y−21
x=(8)(3)−21
x=3(Simplify both sides of the equation)
The equation is y= -2x + 3.
The 3 is the y-intercept and how I got -2 was that I did rise/run. It went down 2 times and over once so -2/1, which will give you simply -2.
