Question

Giving medals!!!

Choose the equation below that represents the line passing through the point (2, -4) with a slope of one half.

y = one halfx + 5

y = one halfx - 3

y = one halfx - 5

y = one halfx + 3

Answer 1

r u familiar with the poin-slope formula

Answer 2

yes

Answer 3

great y-y1= m(x-x1)
can u tell me what y1, x1, and m stand for

Answer 4

That well, I'm not so sure about!

Answer 5

k
y1--> ur given y coordinate which is -4 in this case
x1 --> x coordinate --> 2
m--> slope -->1/2
confused?

Answer 6

Totally confused, yes

Answer 7

the question says the line passes through the point (2,-4) whats our x and y from the given ordered pair ?

Answer 8

(2,-4)?

Answer 9

or 1/2?

Answer 10

1/2 is the slope

Answer 11

does that make sense

Answer 12

Yes.

Answer 13

so whats the y and x coordinate

Answer 14

I was thinking it's (2,-4). Is it not?

Answer 15

thats an ordered pair the x is 2 and the y is -4

Answer 16

oh, okay

Answer 17

what is the slope

Answer 18

1/2

Answer 19

good emphasis @Godlovesme

Answer 20

thanks :) @dtan5457

Answer 21

lets use the point-slope form which is y-y1 = m(x-x1)
y1 -- ?
x1-- ?
m--? can u try @FEARLESS_JOCEY :)

Answer 22

I never really got how to do this slope formula, so Idk if I could be able to accurately, solve the formula or plug it in.

Answer 23

@FEARLESS_JOCEY

You can also solve this simply using y=mx+b. As your answers are all in that form. It would be more convenient.

Answer 24

its alright :)
we are only given one ordered pair so it doesn't matter if it says x1 or x its still the same thing so x1 --> 2 and y1-->-4

Answer 25

y=mx+b

y=-4
m=1/2
x=2

Solving for b.

Answer 26

can u plug those @FEARLESS_JOCEY
