Enter your answers as a whole number

The x-intercept is
.

The y-intercept is

Answer 1

i know how to do this normally, you replace the other with a 0 and solve it, but i dont get a whole number when i do that for this problem, im confused :/

Answer 4

"Enter your answers as a whole number"
it actually says it does

Answer 5

Let's first write this in slope-intercept form :)

First distribute `4` into the paranthesis.

\(\huge\bf{4(x-5) \rightarrow 4 \times x + 4 \times -5}\)

What does that equal?

Answer 6

yep. 4x - 20

Answer 7

Now we have...

\(\huge\bf{y+8=4x-20}\)

we subtract 8 from each side.

\(\huge\bf{y=4x-28}\)

Got it?

Answer 8

yep, i got to that point :P

Answer 9

X - intercept = `(#,0)`

Y - intercept = `(0,#)`

To find the `x - intercept` we would plug in 0 as `y` in the slope-intercept equation.

\(\huge\bf{0=4x-28}\)

Simplify to find x.

Answer 10

ah okay i gotcha, so x = 7

Answer 11

and y = -28 okay, okay, thats what i got the first time, but i didnt think it was right

Answer 12

Nicely done ;)
