The answer to the first question would be 1% of the purchase price and the answer to the second question would be 0.5 % of the purchase price.
The slope of the line is 2.
<u>Step-by-step explanation:</u>
The given points are (5,-3) , (6,-1) , (7,1) , (8,3).
To find the slope of the line that contain these points is calculated by the slope formula.
Slope = 
Take any two points from the given set of points.
Let,
(x1,y1) = (5,-3)
(x2,y2) = (6,-1)
Slope =
⇒ 2
Therefore, the slope of the line is 2.
Similarly, the slope of the line can be known by using any two points on the line in the slope formula.
(The answer is 12.082.) Juan used 12.082 meters of rope.
Answer: g(x) transforms the function so that the graph of the function f(x) shifts vertically by 4 units. For instance, if f(x) is a line intersecting the origin, the transformed function g(x) will be a line with same slope but with a y-intercept at 4.
