The formula of a slope:

We have the points (1, 4) and (1, -3). Substitute:

DIVISION BY ZERO!!!
Answer: The slope is undefined.
It's a vertical line x = 1.

Answer:
200
Step-by-step explanation:
25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.
By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)
Explanation:
To find if 0 is greater than -1 we can graph these values on a number line. If 0 is to the left of -1 then is less than -1, if it's to the right, then it's greater than -1:
Answer:
Yes, 0 is greater than -1.
f(x) + c -> up by c
f(x) - c -> down by c
f(x + c) -> left by c
f(x - c) -> right by c
For y = f(x + c), the y value of x now takes the y value of the function of x + c, or the one c to the right of x, shifting the entire graph left by c.
