Question

1. Let f(x)=3x-10. Find the value of f(-3)
a. 21
b. -1
c. -19

2. Find the slope of the line that passes through (3,-4) & (-1,2).
a. 2/3
b. 3/2
c. -2/3
d. -3/2

3. Find the slope of the line passing through (4,9) & (-2,9).
a. 0
b. underfined

Answer 1

Please, please help.

Answer 2

\[f(x)=3x-10\]
\[f(-3)=3\times (-3)-10\]

Answer 3

And, do I just solve it like that?

Answer 4

Find the slope of the line passing through (4,9) & (-2,9).
since the \(y\) values are the same, the slope is \(0\)

Answer 5

yes, compute \(3\times (-3)-10\) and that will be your answer

Answer 6

Oh, okay, thank you! So, so much! Can you do the third one?

Answer 7

Sorry, 2nd

Answer 8

i wrote the answer to the third one above

Answer 9

\((3,-4) , (-1,2)\) slope is
\[m=\frac{-4-2}{3-(-1)}\] compute that number

Answer 10

Thank you, thank you, thank you!

Answer 11

yw
btw you do it carefully, you should get \(\frac{-6}{4}=-\frac{3}{2}\)

Answer 12

Oh, okay! I forgot to simplfy.

Answer 13

The x in 3x(-3)-10 I'm confused what I do with it
