Question

5 questions, can some please check them

Answer 1

1: what is the equation of the line?
A: y = -3/2x
B: y = -2/3x
C: y = 2/3x
D: y = 3/2x
I got C

Answer 2

2: Points A and B lie on the graph of the equation y = −4.3x.

What are the y-coordinates for each point?


I got -3, 12.9 and 5, 21.5

3:Choose the correct answer.
Determine whether the given has a positive slope, a negative slope, a zero slope, or an undefined slope.

A.
negative slope

B.
undefined slope

C.
zero slope

D.

I got zero slope
positive slope

Answer 3

4: What is the slope of the line passing through the points (1, –5) and (4, 1)?
i got 2

Answer 4

5:Which is the graph of y=1/2x

Answer 5

I got BB for the 5th one

Answer 6

1. C is correct
2. Wrong sign for one of the values, values are correct
3. Zero slope is correct
4. 2 is correct
5. Nope, wrong sign again!

Answer 7

so, what did I do wrong on 5 and 2

Answer 8

I am sure you'll find the problems if you redo the calculations.

Answer 9

ok

Answer 10

I think 5 is Cc

Answer 11

cc is correct for 5, since it is a positive slope.

Answer 12

Remember, when the slope is negative, such as
y=-2x, x and y have different signs, unless x=y=0.

Answer 13

oh, ok

Answer 14

I wasn't sure for number 2 to put decimal points or commas

Answer 15

If you are in the US, points are usually expressed as
(-3, 12.9) for a point.
In Europe, decimals are replaced by commas.

Answer 16

I'm in us

Answer 17

So the form (-3, 12.9) would be correct for the first point.
You just have to make corrections for the second point.

Answer 18

Okay

Answer 19

Did you find the correction needed?

Answer 20

yeah

Answer 21

ty very much :)
