SOLUTION: Plot the equation 3x + 4y = 7 on the graph paper taking four points. Also plot the equation y = x on the same graph paper. At what point do the two lines meet?

Question 786417: Plot the equation 3x + 4y = 7 on the graph paper taking four points. Also plot the equation y = x on the same graph paper. At what point do the two lines meet?

3 x + 4 y = 7 .............1
generate values of y for x
(1,1)(3,-1/2)(5,-2)(-5,11)
-1 x + 1 y = 0 .............2
(1.1)(2,2)(5,5)(7,7)

They intersect at (1,1)
