Answer:
1050 units
Explanations:
Given the equation y=500+0.2x to determine his weekly paycheck based on his sales volume, where:
y is the amount of his check
x is the number of units he sells each month.
In order to determine the amount of units he would need to sell for his paycheck to be $710, we willl substitute y = 710 into the equation and find the value of x as shown:
y=500+0.2x
710 = 500+0.2x
710-500 = 0.2x
210 = 0.2x
0.2x = 210
Divide both sides by 0.2
0.2x/0.2 = 210/0.2
x = 1050
Hence he would need 1,050 units to sell for his paycheck to be $710

Answer:
y = -2
Step-by-step explanation:
The given line is a vertical line, so a perpendicular line will be a horizontal line. It will have an equation of the form ...
y = constant
In order for the line to go through the given point, the constant in the equation must be the same as the y-coordinate of the point: -2.
Your perpendicular line is ...
y = -2
I’d say the answer would be d
