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
