Question

Find the slope of the line passing through (4, 9) and (-2, 9)

A. 0
or
B. undefined

Answer 1

\[\huge {\color{blue} {m=\frac{y_1-y_2}{x_1-x_2}} }\]

plug in your points.

Answer 2

I don't understand how to plug in. I was absent and the teacher gave me this as home work which I don't understand. :/

Answer 3

OK.
\[\huge {\color{blue} {(x,y)} }\]this is a REGULAR COORDINATE.
plug in the \[\huge {\color{blue} {4} }\huge {\color{blue} {\And-2} }\]for X s
and
\[\huge {\color{blue} {9\And9} }\]for Y s.

Answer 4

Ok brb

Answer 5

???

I'll give you an example, ready?

Answer 6

Sure

Answer 7

Find the slope of the line passing through (3, 4) and (-1, 5).

Answer 8

\[\huge {\color{red} {m=\frac{y_1-y_2}{x_1-x_2}} }\]this is the slope formula.
your points are, (3, 4) and (-1, 5)
plug them in LIKE THIS.

Answer 9

\[\huge {\color{blue} {\frac{4-5}{3-(-1)}⇒\frac{4-5}{3+1}⇒\frac{-1}{4}⇒-\frac{1}{4}} }\]

Answer 10

So the slope is, \[\huge {\color{green} {-\frac{1}{4}} }\]

Answer 11

Do your question the same way.
