Question

What is the slope of the line through the points (5, 2) and (5, -3)

Answer 1

The slope can be calculated if you have two points by: \(\dfrac{\Delta y}{\Delta x}\).

\(\Delta y\) is the difference of the y-coordinates of the points,
\(\Delta x\) is the difference of the x-coordinates of the points.

Put the values you have here in the formula and see what happens...(you have been warned)

Answer 2

which is y and x

Answer 3

x is always the first number, y the second.

Answer 4

(x, y)

Answer 5

i thought it was m= y2 - y1/ X2 - X1

Answer 6

M = -3 - 2/ 5 - 5

Answer 7

The formula you named is the same as what I said: (-3-2)/(5-5). Brackets are needed to avoid confusion...

What about the result of this calculation?

Answer 8

-5/0

Answer 9

-5 correct

Answer 10

Not correct, I'm afraid. Division by 0 is impossible!

Answer 11

so it is undefined

Answer 12

It is, as it is with all lines that are vertical...

Answer 13

so i would put x = -5 ?
