What is the x-intercept of the line given by the equation x minus four y equals twenty?

The x-intercept is 0.

The x-intercept is –4.

The x-intercept is 5.

The x-intercept is 20.

Answer 1

? Help!

Answer 2

The equation is: x - 4y = 20
The graph may look something like this.


To find the x-intercept we know that the y value MUST be 0, do you know why?
Because the x-intercept is the point where the line touches the x-axis, and when the line toughes the x-axis, the y-value of the point is zero [No Rise].

So put y=0
And find the value of x.

Understood this? :)

Answer 3

20 @hotgurl72

Answer 4

OK. But he says it's 20. ?

Answer 5

Which is it, 20 or 0?

Answer 6

@hotgurl72
Did you get my explanation? :)

Answer 7

YEs. I guess.

Answer 8

I told you to put the value of y=0.
And then just find 'x'! :D

Because if the equation given to you is, x-4y = 20
Then you can easily get the value of x!

Try now, what do you think the answer is? :)

Answer 9

What is the y-intercept of the line?

Graph shows a line with negative slope running through points four comma zero and zero comma six

The y-intercept is 0.

The y-intercept is 4.

The y-intercept is 6.

The y-intercept is Negative six.

Answer 10

The answer as @rvc said is 20.

This is because,

x-4y = 20

ALWAYS REMEMBER:
To find x-intercept y=0
To find y-intercept x=0

Here we have to find the x-intercept. So y=0

x - 4(0) = 20
x - 0 = 20
x = 20

Thus, that is the x-intercept of the line [x=20].

Did you get WHY this is the case?

Answer 11

Help?

Answer 12

Now try finding out the y-intercept of your new question from the hints I have given you. :)

Answer 13

So x is 20, not 0?

Answer 14

Just say yes or no please.

Answer 15

It's 20.

Answer 16

yes!
