3.5 hours of studying to get a 75 on the exam.

Step-by-step explanation:

The y intercept in the graph is 40. This means that the constant in the linear equation is 40.

The slope of the equation is 10 because after the variable x travels one interval, the y travels 10.

To get the hours a student need to get 75 on the exam, we set the equation equal to 75.

75 = 10x + 40 where x = hours studied.

75 - 40 = 10x

x = 35/10

x = 3.5 hours

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one
