Answer:
x = 2
Step-by-step explanation:
y = - 5 is a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
Where c is the value of the x- coordinates the line passes through.
The line passes through (2, 7) with an x- coordinate of 2, thus
x = 2 ← is the equation of the perpendicular line
Okay, Jackie starts with 350 mailboxes, but has delivered to 150, so she only has to deliver to 200 more. She can deliver to 50 mailboxes per hour. So 200/50 = 4. The answer is 4 hours.

The answer is "A" i think not 100% sure
tell me if wrong
Answer:
y = 3x -1
Step-by-step explanation:
When the given points are dilated by a factor of 1/5 about the origin, each of the coordinate values is multiplied by 1/5. The points after dilation are ...
... (2/5, 1/5), (-1/5, -8/5)
The line through these points can be found starting with a 2-point form of the equation for the line.
... y -y1 = (y2 -y1)/(x2 -x1)·(x -x1)
Filling in the point values gives ...
... y -1/5 = (-8/5 -1/5)/(-1/5 -2/5)(x -2/5)
... y = (-9/5)/(-3/5)(x -2/5) +1/5 . . . . simplify parentheses, add 1/5
... y = 3x -1 . . . . . simplify

The graph shows the original points and the line through them in red, and the dilated points and line in green.
Answer:
y>=2x-2
Step-by-step explanation:
You're gonna want to make one side equal to zero so subtract 8 from both sides
8x-4y-8 ≤0
Then you want to move the x and the constant back over by adding (-8x+8)
-4y ≤-8x+8
Then you'd flip the inequality sign and divide both sides by 4
y>=(8/4)x-(8/4)
Then you'd break the big numbers and make them exponents
y>=(2^3/2^2)x-(2^3/2^2)
Then you reduce the fraction by removing what appears in the numerator and denominator which in this case is 2^2
So your answer is: y>=2x-2
