OK.
I did add some more to post 3 but I'll show you how to get the y intercept without knowing that equation.
As the gradient is minus 4, that will mean for every 1 you step left in the x direction, the y coordinate will go up by 4.
So step back a few points like this:
(5,0) ... (4,4) ... (3,8) ... (2,12) ... (1,16) ... (0,20)
So the y intercept is (0,20)

Thanks,
I know the formula, I think I need to know how to find the y-intercept to keep going from here because I know how to do it with both intercepts,
if you could help me find out how that would be great

The point gradient form looks like this:
You are told that m = -4 and that (5,0) is one point. So

hi ac88218
just typing this up. Stay on-line if you can.

hello,
Just wondering if anyone can help me out with this question my teacher set me, thanks
"Find the equation of a line with a gradient of -4 and an x-intercept of 5"
hope someone can help...
