I think that they are asking you for the lines with the given information. Linear equations can be expressed as:
y=mx+b where m=slope and b=y-intercept, for the first you are given the slope is -7 so:
y=-7x+b, using the point given (1, -2) you can now solve for b...
-2=-7(1)+b
-2=-7+b, so b=5 thus the line is:
y=-7x+5
....
Same as above...
y=4x/3+b, using point (-3, -5) we have:
-5=4(-3)/3+b
-5=-4+b, so b=-1 thus the line is:
y=4x/3-1 or more neatly...
y=(4x-3)/3
