Question

graph the line
y=5x-5

Answer 1

do you have graph paper at home?

Answer 2

no:(

Answer 3

:(

Answer 4

how ya gunna do this then?

Answer 5

gunna manually draw it with blue pens? or print off some grid paper?

Answer 6

i really dont know how to do it thats why im on here

Answer 7

The -5 in y = 5x - 5, means the line lands on -5 on the y - axis. So mark -5 as a point. Next, since 5 is the slope and slope is rise/run ( 5/1) go up 5 spaces and over 1 space, which is your next point. Then connect the points and you have your line.

Answer 8

Sorry, was afk for a bit. Well you can draw out some stuff like this:

Answer 9

thanks! i have to do two more of these though...

Answer 10

Then you start plugging in values for x. IE: 1, 2, 3, 4... etc. Just a couple and then you'll have figured out what you're line will look like.

Answer 11

The formula is y = mx + b , the b is a point on the y-axis, the m is the slope (rise/run) which you count from the point b.

Answer 12

http://incompetech.com/graphpaper/plain/ You can click, downloadPDF and you'll have graph paper. If you have a printer, than print some off. It'll making graphing these things a whole heck of a lot easier.
:D

Answer 13

ok but now theres a slope with a fraction..

Answer 14

Thats fine. It's just counting Rise (up) and run ( side to side) for example 3/4 would be up 3 and right 4 counting from point b.

Answer 15

or if it's negative like -3/4 or 3/-4 would be down 3 and right 4 or up 3 and left 4.

Answer 16

so the slope is y=-1/4x+3

Answer 17

Yes. The slope would be down 1 and then right 4 units starting at y = 3.

Answer 18

y = 3 which is a point in that equation because b is 3.

Answer 19

ok so the points are 3 for the y axis and then whats x?

Answer 20

remember y =mx+b, m=slope and b=y-intercept aka, where it goes through the y-axis.

Answer 21

points on the x axis you would usually see AFTER you get the line.
