You can put this solution on YOUR website! To find the x-axis intercept, let y = 0 and solve for x
To find the y-axis intercept, let x = 0 and solve for y
.
3x-6y=-18
3x-6(0)=-18 [Let y=0]
3x=-8
3x/3=-18/3[solve for x]
x=(-18/3)
x = -6
Plot points (-6, 0)
equation 1 x-axis intercept= (-6, 0)
.
3x-6y=-18 [Let x=0]
3(0)-6y = -18
-6y = -18
-6y/-6 = -18/-6
y = 3
Plot points (0, 3)
equation 1 y-axis intercept = (0,3)
.
3x+5y=15
3x+15(0)=15 [Let y=0]
3x=15
3x/3=15/3 [Solve for x]
x=5
Plot points (5, 0)
equation 2 x-axis intercept= (5, 0)
.
.
3x+5y=15
3(0)+5y =15 [Let x=0]
5y = 15 [Solve for y]
5y/5=15/5
y = 3
Plot point (0, 3)
equation 2 y-axis intercept= (0,3)
