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
