Answer:
A) (-6, 8)
B) (x, y) ⇒ (-x, y)
Step-by-step explanation:
B) The rule for reflection across the y-axis is that the x-coordinate changes sign:
(x, y) ⇒ (-x, y)
__
A) To find the pre-image point, one can simply reflect the image back across the y-axis:
A'(6, 8) ⇒ A(-6, 8)
Answer:
D
Step-by-step explanation:
Answer:
The first image.
x | y
-4 | 0
0 | 20 <--- When x = 0, the y value is the y-intercept.
4 | 40
8 | 60
Step-by-step explanation:
To check the slope, we can use the equation (y₂ - y₁) ÷ (x₂ - x₁) using any two pairs given. For this example, I'll use (-4, 0) and (4, 40).
x₂ y₂ x₁ y₁
(0 - 40) ÷ (-4 - 4)
(-40) ÷ (-8)
<u>Slope = 5</u>
