Question

can someone check this for me please
Write the equation of the line passing through the points (-6,1) and (-4,2).
My answer: y2-y1/x2-x1
2-4/-2-0
Slope= 4
y=mx+b
m=Slope B=Y intercept
y=4x+4 <--- is this right?

Answer 4

I think you need to check the slope...

(2 - 1)/(-4 - (-6)) =

Answer 5

i got 0.5 @campbell_st

Answer 6

so is it y=.5x+4

Answer 7

great... that's a big help...

so here is a short cut...

the slope intercept form is

y = mx + b

you know m... so its

y = 0.5x + b

pick either point say (-4, 2) if you substitute these into the equation you can find b, the y-intercept

2 = 0.5*(-4) + b

or

2 = -2 + b

what's the value of b...?

Answer 8

2?

Answer 9

@campbell_st

Answer 10

No @Blondebeauty it is not 2

Answer 11

Than i dont get it

Answer 12

-2+2 is 0, not 2.

Answer 13

ok... what do you add to -2 to get and answer of 2..?

Answer 14

^

Answer 15

-2+2 is 0, and 0 + 2 is 2, so add those together:
2+2=4, so b is 4

Answer 16

@Blondebeauty

Answer 17

-2+4 equals 2

Answer 18

Correct

Answer 19

Good job! :)

Answer 20

so the equation should be 0.5x+4

Answer 21

that's correct so the y-intercept is y = 2 so b = 2

then the equation, using your information is

y = 0.5x + 2

Answer 22

oh okay
sorry got ahead of myself

Answer 23

you can use the other point x = -6 and y = 1 so see if it's correct...

Answer 24

Okay thank you

Answer 25

It’s ok @Blondebeauty but yes @campbell_st is right

Answer 26

...Happy studying! :)
