Answer:
The slope is 
Step-by-step explanation:
∵ The rule of the slope passing through 2 points is:
m = 
∵ The points are (7 , 8) and (-7 , 1)
∴ m = 
Answer:
To figure out if 2 lines are parallel, compare their slopes. You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines. If they are the same, then the lines are parallel.

Answer:
60
Step-by-step explanation:
First, divide 120 by two and get 60. Now do 120-60 to get 60. Set up proportion
60/x = x/60.
Cross multiply
x^2 = 3600
and now find the square root of 3600
60
Scale factor is equal to 1/2, since the point went from 10 to 5
