Question 68124: Find the slope and y-intercept.
x = -4
a)Slope:0;y-intercept: (0, -4)
b)Slope: Undefined; y-intercept: (0, -4)
c)Slope: 0; y-intercept: none
d)Slope: Undefined; y-intercept: none
Any help with this problem would be helpful. Thanks

You can put this solution on YOUR website! Find the slope and y-intercept.
x = -4
a)Slope:0;y-intercept: (0, -4)
b)Slope: Undefined; y-intercept: (0, -4)
c)Slope: 0; y-intercept: none
 Slope: Undefined; y-intercept: none
Whenever you have x=k, where k is any number and there is no y, you have a vertical line going through k, in this case -4.
Vertical lines have undefined slopes. They do not cross the y-axis, however, x=0 is y-axis. Therefore, the answer is d.
Happy Calculating!!!
