Question 573840: i'm having problems putting the answers on to to graphs, for example

3x+4y=12

You can put this solution on YOUR website!
put into y-intercept form y=mx%2Bb
3x%2B4y=12subtract the x from bothsides
4y=12-3x divide by 4
y=3-%283%2F4%29x match the formula
y=%28-3%2F4%29x%2B3
m=%28-3%2F4%29 b=3
b is the y-intercept m is the slope
one point is (0,3)
second point is going down from that point by 3 and to the right 4
i got this from negative 3 with means down 3 and positive 4 which means to the right 4
(4,0)
.
plot your points(0,3)(4,0)
draw your line
