1. i have the equation y= -3 + 4 how do I plot that on a graph I dont understand how to , what coordinates are there

Do you mean or ?

Assuming you don't mean

Are you missing an x? If you are not then it is y = 1 which is a horizontal line through the coordinate (0,1).

If that's the equation then the graph should look like that.

Plug in values of x at x=1,2
e.g at x=1 Y = -3(1)+4 = 1 : plot point (1,1)
at x=2 Y=-3(2)+4 =-2 : (2,-2)
now just connect your two points and keep going, since it's a straight line you don't need any more points

There's a very simple trick to this. Have you ever seen before?

Yes I have heard of it I know that M is the gradient and C is the Y intercept but I don't know where to go from there

Yeah, so 4 is the y-intercept. Do you know how to work out the x-intercept? Think about what you have to substitute into y to find it.

In this case and

Meaning the graph goes through the point and goes 3 points down for every point to the right.
