I REALLY NEED HELP :( how to find whether a person is fake or real

Please mark me as the brainliest!

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
