Answer:
x y
0 -2
4 -1
8 0
Step-by-step explanation:
y + 2 = 1/4 x
Subtract 2 from both sides.
y = 1/4 x - 2
Now let x equal each value of x in the table and solve for y.
x = 0
y = 1/4 * 0 - 2
y = -2
x = 4
y = 1/4 * 4 - 2
y = 1 - 2 = -1
x = 8
y = 1/4 * 8 - 2
y = 2 - 2
y = 0
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
Answer:yes yes well Manuel
