Question

Write an equation of a line that passes through the point (2, 3) and is parallel to the line y = 3 over 2x + 5. (5 points)
Select one:
a. y = negative 2 over 3 x
b. y = negative 2 over 3 x − 7
c. y = 3 over 2 x
d. y = 3 over 2 x + 7

Answer 1

Could someone help me please?

Answer 2

Please someone help

Answer 3

If two lines are parallel, they must have the same slope

Answer 4

I feel so stupid! So now what?

Answer 5

So the slope would be 3/2

Answer 6

right now use the point slope formula, do you know it.

Answer 7

I know the slope formula, is it the same?

Answer 8

Or alternatively using y=mx+b plug in your x and y and solve for b.

Answer 9

No the point slope formula is (y-y1)=m(x-x1) where x1,y1 is a point and m is the slope

Answer 10

Ok. So would I plug it in like this: 3=3/2(2)+5 ?

Answer 11

If your going that way it would be 3=(3/2)2+b

Answer 12

Which will yield b=0

Answer 13

so your answer is y=(3/2)x

Answer 14

Oh, ok. Thank you so much! Could you help me with one more?

Answer 15

Sure

Answer 16

A segment with endpoints A (2, 1) and C (4, 7) is partitioned by a point B such that AB and BC form a 3:2 ratio. Find B. (5 points)
Select one:
a. (3.2, 1.6)
b. (3.2, 4.6)
c. (3.8, 3.4)
d. (4.4, 5.8)

Answer 17

Well multiple ways to do it but perhaps the easiest would be to find the change in x and the change in y and take 3/5 of each and add it to A.

Answer 18

Ok, hold on. Let me try to do it

Answer 19

I got (1.2, 3.6) when I found the change in x and y and took 3/5 of it

Answer 20

Sure now add it to A.

Answer 21

So (2, 1) added to (1.2, 3.6) would be (3.2, 9.6). Is that right?

Answer 22

3.2,4.6

Answer 23

Oh sorry, typo. That's the answer?

Answer 24

Yes, choice B

Answer 25

Oh my gosh, thank you so much! :)

Answer 26

Glad I could help

Answer 27

Thank you so much!
