Question

What is the slope of the line that passes through the given points? (6, –1) and (–3, –1)
I used the midpoint formula and got
(3/2,-1)

But my answer choices are
undefined
0
–2 over 3
–3 over 2

What did I do wrong?

Answer 1

the slope formula is
\(\huge m=\dfrac{y_2-y_1}{x_2-x_1}\)

Answer 2

the midpoint formula is to get the midpoint of a segment, not the slope of the line :)

Answer 3

try the slope formula instead...

Answer 4

whats y2-y1 ?

Answer 5

-1--1?

Answer 6

yes,
and thats -1+1 = ... ?

Answer 7

because 2 negatives become positive :)

Answer 8

It becomes 0

Answer 9

so the slope is also .... ?

Answer 10

0?

Answer 11

correct!

Answer 12

slope is 0
so y+1=0
y=-1
