Question

Solve the following simultaneous equations graphically: 3 – – 2 = 0 and 2 + – 8 = 0 Plot only three points per line. Also, write down the co-ordinates of the point of intersection

Answer 1

Answer:

y=3-2x and y=-8-2x.

Step-by-step explanation:

if, x=3,y=3-2(3),=3-6,=-3

if, x=2,y=3-2(2),=3-4,=-1

if, x=-2,y=3-2(-2),=3+4,=7

if, x=3,y=-8-2(3),=-8-6,=-14
