Question

Find the slope of the line through the pair of points. A(2, –3), P(2, 9)

A. 0

B. 2/3

C. - 1/3 -1/3

D. undefined

Answer 1

Given any two points
\[\large (x_1, y_1) \ and \ (x_2, y_2)\]
The slope of the line through them is given by
\[\huge \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 2

However, in this case, you seem to end up with
\[\frac{9-(-3)}{2-2}=\frac{12}{0}\]
Which is undefined.

By the way, if the slope of a line is undefined, it means the line is vertical.
(if the slope is zero, the line is horizontal)

Answer 3

so i will choose D

Answer 4

That's right.

Answer 5

One more
x+y=3
y=2x-15

A. (5 -5)
B. (-10, -5)
C. (1, 2)
D. (6, -3)

Answer 6

i think its "D"

Answer 7

You're right. Again, I hope you arrived at the answer the correct way... (although if you were pressed for time, trial and error may be quicker if you have choices)

Answer 8

-1/3x + y = –1

y = 4 + 1/3x

A.

infinitely many solutions

B.

no solution

C.

no solution

D.

infinitely many solutions

Answer 9

CHOICE A

Answer 10

CHOICE B

Answer 11

CHOICE C

Answer 12

CHOICE D

Answer 13

Which one do u think

Answer 14

Try to set up both equations so that y goes (alone) on one side, and everything else on the other.

Answer 15

In the second equation, it's already done for you. Let's do the first...
y = (1/3)x - 1
Am I right?

Answer 16

Well, anyway, your lines are parallel, and they do not intersect anywhere, ergo, there are no solutions.

Answer 17

so wat would be the answer

Answer 18

No solutions. It's in your choices.

Answer 19

Write a rule for the linear function in the graph.



A. y = -4x + 13

B. y = -4x – 13

C. y = 4x – 13

D. y = 1/4x – 13

Answer 20

You have two points marked on your graph. In each of these choices, substitute both points. There is only one equation here that would satisfy both points.

Answer 21

This isn't the proper way to solve this, but time's not on our side... I have to go for now.
