find x when y = 45.
2. suppose y varies inversely as x and y=24 when x= 3.
find x when y = 36
*write the point-slope form of an equation for the
line passing through the point at (3,-6) with slope
-4/3
3. write an equation in slope-intercept for the line
through point (2,4)and (6,-2)
4. determine the slope and y-intercept of the graph of
