Question

Line M passes through points (4,2) and (-7,1). What is the slope of a line N that is parallel to line M?


11

1/11

-1/11

Answer 1

Answer 2

We just need to find the slope of line M using the two points.
Because if N is parallel, it has the same slope.
Do you know how you'd find the slope using the points?

Answer 3

not really

Answer 4

The slope will be the difference between the y values, divided by the difference between the x values

Answer 5

So how would you calculate that?

Answer 6

im lost to say the truth

Answer 7

do i divide 4,1 and 2,-7 or what?

Answer 8

We can use this formula to calculate it:

\[M \space = \frac{ y _{1} \space - y _{2} }{ x _{1} \space - x _{2} }\]

Answer 9

The top should be the y values from the two points
What will those be?

Answer 10

4 and 1?

Answer 11

Nope. Let me give a hand:
An ordered pair is always (x,y)
So the y values are the second number in each point

Answer 12

ohh so -7 and 1?

Answer 13

The first point is (4,2)
The first number inside parentheses is x

And the second number inside parentheses is y
So in (4,2), what would the y value be?

Answer 14

In the point (4,2), x is 4 and y is 2
Does that make sense?

Answer 15

my bad

Answer 16

im just tires

Answer 17

so what would the two y values on top be?

Answer 18

so 2 and 1 right?

Answer 19

Yes

Answer 20

And what would the x values be?

Answer 21

4 and -7

Answer 22

\[\frac{ 2 \space - 1 }{ 4 \space - (-7) }\]

So now you subtract them on the top and bottom
What would that give you?

Answer 23

1/11?

Answer 24

wait so the answer is 1/11?
