Question

What is the y-intercept in this linear equation?y = -4x + 4

Answer 1

The y intercept is defined where x = 0. What does that give us? ...

Answer 2

set x equal to zero

Answer 3

y=-4(0)+4
y=0+4
y=4

Answer 4

There you go!

Answer 5

well looky there

Answer 6

Also good to note that with a linear equation like this, you can use the slope intercept equation

y = mx + b
and 'b' is your y-intercept

so your

y = -4x + 4
y = mx + b

as you can see (and have shown above...the y-intercept is 4
