You could multiply x+2 by any number, and it would have the same x intercept, which is -2. For example: y=2x+4; or y=3x+6; or y=4x+8; or y=-x-2

y = -2x+4 It can be any equation providing the slope is the same but the y intercept is different
It is: y = 2x+6 or any other equation that has the same slope as 2 but with a different y intercept
4x+y = 14 will be parallel to the above equation because the slope or gradient remains the same but the y intercept changes.
We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
