Rubbish drawings I know but I really need help with these 4. CHeers!

Sorry for posting again, but I just realized these are the actual questions:

A line that passes through (0,7) at a gradient of 3.
^I Think this one is 3x+7^

A line that passes through (2,3) at a gradient of 2.
A line that passes through (4,3) at a gradient of -1.

A line that passes through (2,1) and (4,5)
A line that passes through (5,4) and (6,7)
A line that passes through (0,5) and (3,2).

Please confirm for me these are the final answers and they dont need simplifying...

A line that passes through (0,7) at a gradient of 3 = 3x+7
A line that passes through (2,3) at a gradient of 2 = y= 3 + 2(x - 2)
A line that passes through (4,3) at a gradient of -1 = y= 3 - (x - 4)

ryos wrote:

y= 3 + 2(x - 2)
y= 3 - (x - 4)
y= 1 + 4.5(x - 2)

etc.

Are these the final answers? I'm unsure.
