Question

Can someone explain the whole concept of solving systems by graphing?
I GIVE MEDALS!!!!!!!

Answer 1

Some problems can be represented by lines. The problems that are solvable by systems, when graphed, the 2 lines will intersect at one point, that one point is the answer to the problem.

Answer 2

ok thank you but i meant the formulas for how to turn standard form into slope intercept form

Answer 3

lets take 4x-y=5 as an example. it is in standard form at the moment

when we change it to y=mx+c form ... y=4x-5 it is now in slope and intercept form. the slope is 4 (gradient) and y intercept is at -5

Answer 4

changing equations in standard form to y=mx+c form (gradient and y intercept form) makes it quicker to graph.

Answer 5

thanx for the medal :D

Answer 6

@marigirl Good job!
