Question 322929: Determine the x- and y-intercepts of the given equation. Y=4X+4

You can put this solution on YOUR website! The y-intercept is the y-value of the point where the graph of an equation intercepts the y-axis of the coordinate system. At the y intercept the value of x=0.
So to find the y intercept, set x=0 and solve for y:
y=4x+4
y=4(0) + 4
y=4
So the y intercept is (0,4)
To find the x-intercept (where the graph hits the x axis), you follow the same steps, but set y=0.
y=4x+4
0=4x+4
-4=4x
-1=x
So the x intercept is (-1,0)
