Answer:
The y-value of P' is -10.
Step-by-step explanation:
It was given that; triangle PQR has vertices P(–2, 6), Q(–8, 4), and R(1, –2).
The translation rule is

To find the image of P, which is P', we have to substitute the coordinates of P(-2,6) to obtain;


Hence the y-value of P' is -10.
Answer:
3h² - 11h - 42 = (3x+7)(x−6)
Step-by-step explanation:
We need to find factors of 3h² - 11h - 42. It is a quadratic equation.
We search two numbers such that their product is 42 and sum is 11. So,
3h² - 11h - 42 = 3h² -18x +7x -42
= (3x+7)(x−6)
So, the required factors are (3x+7)(x−6).
Answer:
y = -2
Step-by-step explanation:
The line that is perpendicular to y-axis will be a horizontal line so it's slope is 0 => y = 0x + b or y = b
Using (5,-2) => -2 = b => b = -2
then y = -2
