PLEASE SOMEBODY HELP ITS 11:19 and it’s due at 11:59

4 hours

Step-by-step explanation:

we have to make an equation out of the points given, so the slope is change in y / change in x = 85-80/2-1 = 5 (I used the points 1,80 and 2,85 to find this but it would be the same no matter what two points you took).

then we need to find the y intercept.

we are making it into y=mx+b. m is 5 (the slope) and b is the y intercept.

we find this by plugging the slope into a random point on the chart.

85 = (5)(2) + b

b=75

y=5x+75

to get a 97:

97=5x+75

22=5x

x=22/5 or 4.4 hours, so I'd guesstimate 4 hours
