Question

Solve the system of linear equations by graphing.

y=-12x+3

x+2y=6



Answer 1

Well, you can do this 2 ways...

Graph the first equation, then solve the 2nd for y and graph it (y = mx + b).

Make a table of x-values (perhaps from -2 to 2), plug them into both equations, and get your y-values to graph the points.

x = 0

0 + 2y = 6

y = 3

(0,3) is one point on the 2nd graph.

Where your two graphs cross is your solution. That's the point (thus x and y-value) that will make BOTH equations true.
