last year there 43 science project submitted by the students at the science fair. this year there 52 science projects. To the nearest 10th, what is the percent of change in a number of science project submitted?

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

the answer for this question is 38

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
