Question

Find the y-intercept of the line by substituting 0 in for x and solving for y. y = 4x -12

Answer 1

Answer:

y-intercept = -12

Step-by-step explanation:

The y-intercept is the "y" value when x = 0. You can find the y-intercept by plugging 0 into the equation and simplifying.

y = 4x - 12                                      <----- Original equation

y = 4(0) - 12                                    <----- Plug 0 in "x"

y = 0 - 12                                        <----- Multiply 4 and 0

y = -12                                           <----- Subtract 12 from 0
