A student must find the slope of a line that passes through the points (–1, 1) and (2, 3). Which of the statements below best applies to the sample mathematical work? A. the formula for the slope of the line is incorrect B. the student simplified the expression incorrectly C. the formula is correct, but the student plugged in the x and y values into the slope formula incorrectly D. there are no errors in the work shown

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

find the magnitude of the trig term
