Question

Could someone take a look at this Math problem; I am not good at showing my work, Thank you.

Answer 1

Function B has a rate of change ( or slope) of 11-5 / 3-1 = 6/2 = 3

Function L  y = 6x + 4  has a  rate of change of  6 . Higher than function B.

To find y intercept of function B; 

y = 3x + b  where b = y intercept, when x = -3 y = -7 so
-7 = 3(-3) + b  giving b =  2

y intercept of Function B is 2 and  of function L it is 4

L has greatest y intercept
