Answer:
B
Step-by-step explanation:
The equation of the perpendicular line is y + 7 = -1/7(x - 3)
<h3>How to determine the line equation?</h3>
The equation is given as
y = 7x + 14
Also, from the question
The point is given as
Point = (3, -7)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = 7
This means that the slope of y = 7x + 14 is 7
So, we have
m = 7
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is -1/7
The equation of the perpendicular lines is then calculated as
y = m(x - x₁) +y₁
Where
m = -1/7
(x₁, y₁) = (3, -7)
So, we have
y = -1/7(x - 3) - 7
Evaluate
y = -1/7(x - 3) - 7
Add 7 to both sides
y + 7 = -1/7(x - 3)
Hence, the perpendicular line has an equation of y + 7 = -1/7(x - 3)

I just rounded a bunch for your sister.
463 < 500 so 3463 rounds to 3000
216 < 500 so 4216 rounds to 4000
501>=500 so 2501 rounds to 3000
457<500 so 6457 rounds to 6000
625>=500 so 6625 rounds to 7000
adding up the estimates gives an estimated total: 23000
Division is multiplications opposites so for example if u have 12 crayons and u divide that by 6 you get 2 crayons.
A would be your best option. Choice A properly displays the equation, 5x+6=4x+(-3), using words. Let me know if you want an explanation of why the other options are invalid. :)
