Please help: y=3x?

Answer 1

This is the equation of a straight line of slope (gradient) = 3
Line passes thro` origin.
Some points on the line are:-
(0 , 0), (2 , 6), (4 , 12)

Answer 2

I am not sure what you are looking for here, but y = 3x is the equation of a line. There are a few ways that you could graph this. If you are unsure of what it looks like, I would create a xy table. Choose a value of x and then figure out what y would be.
x | 3x | y
------------
0 | 3*0 | 0
1 | 3*1 | 3
3 | 3*3 | 9
4 | 3*4 | 12
(try some more)

You can then graph these points on a coordinate system:
(0, 0)
(1, 3)
(3, 9)
(4, 12)
You should get a straight line that has a positive slope or goes uphill.

Answer 3

y = 3x is a linear equation with a slope of 3. You can plot this line by setting x = 0 then solving for y which would give you 0. You can then set x = 1 and solve for y again which will give you 3. Now that you have two points (0,0) (1, 3) you can plot and draw a line that represents this equation.

Notice how each time you move one unit on the x axis you have to move three units on the y axis in order to remain on the line? That is where you get the slope of 3.

Answer 4

y/x = 3

Answer 5

This is a straight line with slope=3 and y-intercept = 0.

Answer 6

it only means that y is 3 times the value of x
so if x is 1 y is 3
if x is 2 y is 6
s whatever mayb the value of x , just multiply it by 3 and u get the value of y

Answer 7

what you need
slope=3
x=y/3

Answer 8

So what do you want to know? It would help if you provided more information

y = 3x

x = y/3

Answer 9

it could mean different things
part of equation, equation of line, relation between two variables etc
