Cost of polishing the floor at the rate of 2 rupees per sq.cm = 
Answer:
slope is equal to rise (going up or down on graph) over run (going left or right)

To find the X value of the solution, you would set the two equations equal to each other bu substitution:
if <span>y = -2x + 5 and y = 3x - 2,
</span>-2x + 5 must be equal to 3x - 2
solve for x... you should get 7/5
then, plug that into one of the original equations as X and you would get the Y value, 11/5
This point, (7/5,11/5) is where the two lines cross
