Question

Graph each equation.

Answer 1

y=2
@PeterPan

Answer 2

If this is y = 2....then the graph will just be a horizontal line at the point y = 2....because the line can ONLY go through 1 given point on the y-axis so it MUST be a line going straight through y = 2

Answer 3

anything y = k, just find k on the y-axis, and draw the horizontal line through that point :)

If on the other hand, you have x = h instead, find h on the x-axis, and draw the vertical line thru that point :D

Answer 4

So it would be

Answer 5

yes, more or less :D

Answer 6

Ok :)

Answer 7

x+4y=10

Answer 8

aha tricky...
but graphing lines always involves finding two points on that line and connecting the dots ^.^

Answer 9

I just don't get it :(

Answer 10

Usually these points are what are called "intercepts".
There are two of them, the x intercept, and the y intercept

Answer 11

To get the x-intercept, set y=0, and solve for x.

Answer 12

so x+4(0)=10?

Answer 13

Yup. So x = ?

Answer 14

10 :)

Answer 15

That's right :)
So the x-intercept is the point (10 , 0)

Now to find the y-intercept, this time, set x = 0, and solve for y :)

Answer 16

y=2.5

Answer 17

That's right :)
So the y-intercept is the point (0 , 2.5)
(notice that the 2.5 is the y-coordinate this time, as opposed to the x-intercept (10,0) )

So, everything set?
x-intercept --> (10 , 0)
y-intercept --> (0 , 2.5)

Answer 18

Yes :)
now to graph it c:

Answer 19

So you just find these two points

Answer 20

THANK YOU!!!!!!! :D

Answer 21

And connect the dots... like a kid with a colouring book!!!
XD

Answer 22

:) Did that and Now i'm done >:D

Answer 23

Awsum :)
