Rotating a figure 90° counterclockwise about the origin results in an ordered pair (x, y) mapping to its image (-y, x). Thus point C, which is at (3, 5), will map to (-5, 3).
Answer:
![\displaystyle [-8, -10]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B-8%2C%20-10%5D)
Step-by-step explanation:
12 = x - 2[3x + 14]
12 = x - 6x - 28
12 = −5x - 28
+ 28 + 28

Answer:
Step-by-step explanation:
(x₁, y₁) = (-10, -10) & (x₂, y₂) = (-5, -10)
y-intercept = b = -10
There is no change in y- coordinates. So, the line is parallel to x- axis
Slope = 0
Equation: y = b
y = -10
