The slope formula is

. For the two points,

. You can pick any of the Y and X from these two points, but only once.

=

= 2 or

=

= 2 and both will equal to. The answer for the slope is 2.
The increase is D: 50% because the 1 in the parentheses stands for the 20 that was already there, with the .5 being the amount that’s actually being increased. 0.5 translates to 50%, so the answer is D.
slope = (y2-y1)/(x2-x1)
m =(17-4)/(8-1)
m = 13/7
You have to keep the pairs in the same order
Y = -3/2x + 4
