A student made a table to compare the number of hours she studied to her quiz scores. Do her scores show a proportional relationship? Why or why not? Hours of study | Quiz Scores
2.0 40
3.5. 70
4.0 80
5.0 100

Yes

Step-by-step explanation:

2 hours=40

so 1 hour=20

if we use that:

3.5x20=70 as stated

4x20=80 as stated

5x20=100 as stated

so there is a proportional relationshi.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
