Ms. walker used a coordinate plane to plot her students' scores on a recent quiz. she let x represent the number of correct answers they had on their quiz and y represent the number of points earned. she then plotted the ordered pairs (17, 68), (20, 80), and (24, 96) to represent the data from three students. what is the slope of the graph in points per question?

Slope = 4

Step-by-step explanation:

The x-axis values to represent the number of correct answers.

The y-axis values to represent the number of points earned.

The points on the graph are: (17,68) , (20,80) and (24,96)

The slope(m) of the graph = change in y ÷ change in x

i.e = = 4

The equation of the straight line graph is;

y=4x
