So the equation basically is 3x-2=y. The x intercept is when y is 0. We need to move the equation so it equals x.
3x-2=y
Let's add 2 to both sides.
3x=y+2
Now divide.
(y+2)/3=x
Let's make y=0.
(0+2)/3
2/3=x
So, the x intercept is (0,2/3). We could even look on a graph (below).
3x-2=y
Let's add 2 to both sides.
3x=y+2
Now divide.
(y+2)/3=x
Let's make y=0.
(0+2)/3
2/3=x
So, the x intercept is (0,2/3). We could even look on a graph (below).
