Formulas and Literal Equations

Step-by-step explanation:

Given, , solve for x.

Multiply both sides by 2

Add x to both sides

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
