The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:

now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).

b then equals 16. so, the answer is D.
Answer:
0.96%
Step-by-step explanation:
Well the easy way to do this is
1.262
- - - - - - - x 100 = 100.96%
1.25
( this is just saying, now the thing is 100.96% of it original size)
So now they are asking the increase, so just simply take
100.96 - 100
= 0.96%
