I'll do one, you can do the rest.
Use the slope-intercept form of a line,y=mx%2Bb.
highlight%28y=%281%2F2%29x%2B3%29
Plot the y-intercept, (0,3).

Slope equals change in y over change in x.
m=%28DELTA%2Ay%29%2F%28DELTA%2Ax%29
If I move 2 units in the x, then I need to move 1 unit in the y since the slope is m=1%2F2.

Starting from the point (0,3),
X:0%2BDELTA%2AX=0%2B2=2
Y:3%2BDELTA%2AY=3%2B1=4
(2,4) is another point on the line.
Plot it and then connect the two points with a line,
