Question

What is the x-intercept of the line with the equation

Answer 1

we have to replace \(y=0\) into your equation

Answer 2

Like this?

Answer 3

correct! so, I get this: \(-2x=18\).
Now, please divide both sides by \(-2\), and solve for \(x\)

Answer 4

Do I divide both sides by -2 in the whole equation or just -2x=18?

Answer 5

you have to divide by \(-2\) the whole equation

Answer 6

Okay, I hope I get this right...

Answer 7

hint:

Answer 8

I don't get it how you crossed out the 18 too...

Answer 9

what is \(18/ (-2)=...?\)

Answer 10

-36

Answer 11

I think it is \(-9\), since \((-9) \cdot (-2)=18\)

Answer 12

Ah, you're right my bad. D:

Answer 13

so the \(x-\) intercept is \(x=-9\) :)
