OK PEOPLE I I AM WILLING TO GIVE BRAINLIEST TO THE BEST ANSWER PLEASE HELP QUICK

Step-by-step explanation:

I accidentally skipped c, but you can use the height of week 3 to solve for it.

Since the common height difference is 3 inches, the height for week 1= height of week 3-2(common difference)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
