Question

Explain, in complete sentences, how you would use the graphing method to solve the following system of equations
3x – 6y = 12
9x + 2y = –24

Answer 1

Get both equations in standard form y=mx+c, where m is the gradient and c is the y intercept. Plot both graphs and see where they intercept. The co-ordinates of the interception point is the solution.

Answer 2

just consider value of x=1,2,3 and find value of y at these points when x= 1,2,3 ...you'll have three pair of pints and then you can draw graph...
