Question

Which line has an equation of y=-5x+4 in slope-intercept form?

a line passing through the points (1, 9) and (3, 19)

a line passing through the points (2, –14) and (4, –24)

a line passing through the points (1, 1) and (3, 11)

a line passing through the points (2, –6) and (4, –16)

Answer 1

2nd Option

Answer 2

Do you know the slope-intercept form of a line?
y = mx + b [Where m is slope and b is y-intercept]

Answer 3

yes

Answer 4

So here in this question has a slope of -5.

Answer 5

\[\frac{ -14-(-24) }{ 2-4 }\]
\[\frac{ -14+24 }{ 2-4 }\]
\[\frac{ 10 }{ -2}\]
That's the only option Where slope = -5

Answer 6

Find the slope of all other lines and see which one has a slope of -5

Answer 7

All of them do. :D :p

Answer 8

\[\frac{ y2-y1 }{ x2-x1 }\]

Answer 9

lol

Answer 10

@FilthyMcNasty
Even the last one does.

Answer 11

Oh yeahh??

Answer 12

that kinda confusing so wait the answer is B

Answer 13

No it is either B or D.
So how do you think we'd decide? :D

Answer 14

@andieboo1995 ?

Answer 15

@andieboo1995
Did you understand why the answer has to B or D?

Answer 16

Answer is D.. srry...

Answer 17

Instead of x,y just use any coordinate & see which 1 is TRUE

Answer 18

@andieboo1995 ?
Got it then? :)

Answer 19

y=-5x+4

a line passing through the points (2, –6) and (4, –16)

-6= -5(2) +4
-6= -10+4
-6=-6

Answer 20

ohhhh okay

Answer 21

lol i didnt get it at first @AkashdeepDeb
