Formulas (equations): a = 3x and b = 5x + 1
as x increases, does a or b go up faster?
if x=0, then a=?
if x=1 then b=?

B goes up faster

if x=0, then A=0

if x=1 then B=6

Explanation:

Formulas Or Equations

We have two different formulas

A = 3x

B = 5x + 1.

They both are equations of lines. The number beside the X (coefficient) is also known as the slope of the line. The greater the slope, the faster the function goes up as X increases. We can clearly see that the equation B has a greater slope, which means it goes up faster than A as X increases

When x=0, A=3(0)=0

When x=1, B=5(1)+1=6
