Find the slope (m) by using Y2-Y1/X2-X1
Y2 = -1
Y1 = 7
X2 = 4
X1 = 2
(-1 - 7)/((4-2) = -8/2 = -4
Use the point-slope formula to determine the equation. You only need to use one set of points. (2,7) in this case.
(y-Y1) = m(x-X1)
(y - 7) = -4(x - 2)
y-7=-4x + 8
y= -4x + 15
Answer:
D
Step-by-step explanation:
4x - 2(x + 3) = 8
Use distributive property
4x -2x - 6 = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14 ÷ 2
x = 7
Answer:
Table B
Step-by-step explanation:
Answer:
{(1, 2), (2, -3), (3, 4), (4, -5)}
Explanation:
The <u>domain</u>, or <u>x-value</u><u>,</u> isn't repeated, while it is in the other answer choices, making the others <u>non</u><u>-</u><u>f</u><u>unctions</u>.
