How do you sketch a graph for the following line:
y=7/2x-2
-------
Plot 2 points::
If x = 0, y = (7/2)*0-2 = -2
----
If x = 2, y = (7/2)*2 - 2 = 7-2 = 5
----
Plot:: (0,-2) and (2,5) and draw a line thru them.

to sketch a graph for the line y=%287%2F2%29x-2 all you need is to find two points that lie on a line (easiest is to find x an y-intercepts)
so, set x=0 and find y-intercept
y=%287%2F2%290-2
y=-2
y-intercept is at the point (0,-2)
set y=0 and find x-intercept
0=%287%2F2%29x-2
0%2B2=7x%2F2
2%2A2=7x
4=7x
4%2F7=x
x-intercept is at the point (4%2F7,0)
plot these points and draw a line through:
