Astudent earns a 98 on a test for answering one question incorrectly and earns a 90 for answering five questions incorrectly. is the slope of the line that models the linear relationship a positive negative zero or undefined slope?

This can be solved by solving the slope of the line. First let y be the rating of the test and x be the number of incorrect answers. Slope can be solved using the formula:

M = ( y2 – y1 ) / ( x2 – x1)

M = ( 90 – 98) / ( 5 -1 )

M = -2

So the model has a negative slope
