use data in table to write an equation four your trend line:

apparent temperature due to humidity at a room temperature of 72 degrees F

Humidity 0/20/40/60/80/100

apparent 64/67/70/72/74/76
temperature

possible answer for equation to trend line

answer: y = 2/15x + 64

(y= mx + B)

help...i don;t get it...can you explain step by step....( I get that b is the y intercept which would be when x is 0 so it's 64) ...thank you.
