Question 558861: 120x + 60y= 720 what is the x intercept and the y intercept and is this the equation? Found 2 solutions by mananth, KMST:Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 120x + 60y= 720
60y = -120x+720
/60
y=-2x+12
The y intercept = 12
x intercept plug y = 0
0=-2x+12
2x=12
/2
x=6
The x intercept is 6
You can put this solution on YOUR website! The x-intercept is the point where the line intersects the x-axis, with y=0. Since we all know that the x-intercept point has y=0, we may not complain if you just give us the answer as "x= ..." rather than as the point (x,0).
The y-intercept is the point where the line intersects the y-axis, with x=0.
To find those intercepts just set y to 0 for the x-intercept, and x to 0 for the y-intercept
x-intercept:
120x + 60(0)=720 --> 120x=720 --> x=720/120 --> x=6 or the point (6,0)
y-intercept:
120(0) + 60y=720 --> 60y=720 --> y=720/60 --> y=12 or the point (0,12)
NOTE: Your equation was designed to make finding those intercepts really easy. It could get a little more complicated with other line equations
