Question 73407
Solve the 1st equation for y
{{{x+4y=12}}}
{{{y=3-(1/4)x}}}
Now graph the 2 equations
{{{graph( 300, 200, -6, 5, -10, 10, 3-(1/4)x, -x) }}}Graphs of y=3-(1/4)x and y=-x
The solution is the intersection in the form of (x,y). So if we only had the graph we could estimate the solution to be about (-4,4). I'm just looking at the graph and guessing where they intersect, this intersection is the solution.
