If you have two points on a graph that are (15,22) and (75,92) what would the answer be in y=mx+b format?

I believe the answer is y=7/6x+4.5

(15,22)(75,92)
slope = (92 - 22) / (75 - 15) = 70/60 = 7/6

y = mx + b
slope(m) = 7/6
use either of ur points...(15,22)...x = 15 and y = 22
now we sub and find b, the y int
22 = 7/6(15) + b
22 = 105/6 + b
22 - 105/6 = b
132/6 - 105/6 = b
27/6 = b

so ur equation of the line is : y = 7/6x + 27/6

The answer to your question is b
