Answer:
A) Slope =
explanation:
Take 2 random points off the line, I used (4,1) & (8,2)
The formula to find the slope when given 2 points is
so in this case x1 & y1 are assigned to (4,1)
- 4 = x1
- 1 = y1
and x2 & y2 are assigned to (8,2)
- 8 = x2
- 2 = y2
so substitute the numbers into the formula and solve !
this will result in the answer I got above!!
B) yes it does show a constant rate of change cause it's increasing in 1/4x intervals
C) just because you move the placement of a line on the graph doesn't mean it's going to effect the slope as long as the numbers on the axis don't change!!
<h2><u>Answer</u> : </h2>
By observing the table we can conclude that for the number of years to travel back double the electricity is required .
i.e. for 5 years = 10 megawatts
therefore, the relationship between x and y can be depicted by the following equation :
