The y-intercept is a point on the y-axis.
x=0 at every point on the y-axis.
So if you set x=0 in the equation, it'll tell you the y-intercept.
y = -3(0) + 12
y = 12 .
The x-intercept is a point on the x-axis.
y=0 at every point on the x-axis.
So if you set y=0 in the equation, it'll tell you the x-intercept.
0 = -3x + 12
3x = 12
x = 4 .
