The temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Write the linear equation for this problem in y=mx+b form. Note: this equation has a negative slope (m).

Question

This is similar to the other question.   We know it was 56 deg when we started (y-intercept) and it went down at 1 deg / hr  so it has a slope of -1 so we have:

y= -x+56

agreene · Answer

or y= 56-x if you prefer.
