Question

Which of the following is not a step used when graphing the equation x - 2y = 4 using the
x- and y- intercepts method ?

Answer 1

What are your options?

Answer 2

okay hold on

Answer 3

Plot the y-intercept (0, -2).

Plot the intercept (4, 0).

Count up 1 and right 2 from the y-intercept.

Draw a line through the two points.

Answer 4

those are the options , can you help me

Answer 5

Ok I remember now!:)

This is x and y intercept method:

Make x=0 to find y-intercept.
x - 2y = 4
0 - 2y = 4
-2y = 4
/-2
y = -2
(0, -2)

Make y=0 to find x-intercept
x - 2y = 4
x - 2(0) = 4
x - 0 = 4
x = 4
(4, 0)

And then cross a line through the two points.

The 3rd option is the answer.Why? You only do that step when you change the equation to slope-incercept and solve.

Answer 6

So 3)Count up 1 and right 2 from the y-intercept.
Sorry I took so long to realize that!!!

x- and y- intercept method:
plot x intercept
plot y intercept
cross a line between points

Answer 7

thank you i got it now ! :)
