Answer:
1. y=4x-20
2. y=-2/9x+9/2
Step-by-step explanation:
Parralel lines always have the same slope
the sum of perpendicular lines should always equal -1...therefore the slope is the recirpocal of the given equation...hope this helps :)
Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of

and assuming the line passes through (2, 30) exactly, it would have equation

Answer:
breakdown the initial figure into 2 rectangle
and add their area
The bottom of the ladder is 10.5 feet away from the wall
Step-by-step explanation:
The given scenario forms a right triangle.
Where
The length of ladder will be the hypotenuse
The wall on which the window is situated will ebt he perpendicular and
The distance between the foot of ladder and the wall will be the base
So,
Hypotenuse = H = 20 foot
Perpendicular = P = 17 feet
Base = B = ?
Using the Pythagoras theorem

The bottom of the ladder is 10.5 feet away from the wall
