Find intercepts of the graph of the equation.

1. y = -6

2. y = 3x+9

3 answers

to find the x-intercepts, let y=0
to find the y-intercepts , let x=0
I think I got it right for number 2. My answer is "x=-3" and "y=9".

But I'm confused with number 1, 'cause there is no X.
:/
correct for the first one.

as to the second, you have a horizontal line running 6 units below the x-axis, so it can never cross the x-axis

whenever you have an equation in the form
y = k
it will be a horizontal line k units from the x-axis, so no x-intercept

if you have an equation in the form
x = c
it will be a vertical line c units from the y-axis, so no y-intercept.
