Question

solve x-y=4 and 3x-y=3 graphically

Answer 1

First find the x and y for both equations.

x - y = 4

put y = 0 x will be 4 so (4,0)

put y = 1 x will be 5 so (5,1)

So coordinates for x - y = 4 are
(4,0) and (5,1)

Similarly for 3x - y = 3

put x = 0 y will be -3 so (0,-3)

put x = 1 y will be 0 so (1,0)

So coordinates for 3x - y = 3 are

(0,-3) and (1,0)

So using these coordinates you can plot line on graph for both lines.You can find as many coordinates as you want.
