Answer:

Step-by-step explanation:
The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.
The slope of the line perpendicular to the one shown below will be
because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
Are you asking the equation or the answer
Figure A best represents it because if you add 576 and 49 you get 625, which shows the theorem of a^2+b^2=c^2.
Just subtract 4 each time.
