Question

Choose the correct slope of the line that passes through the points (-4, 8) and (-3, -6).

7

-14

0

14

Answer 1

need help

Answer 2

slope = y2 - y1 / x2 - x1

Answer 3

would be 7 then

Answer 4

so that would give (-6 - 8) / (-3-4) = ?

Answer 5

i got 7

Answer 6

now that would give you 0

Answer 7

sorry, it should be (8 -(-6))/ (-4-(-3))=

Answer 8

how could 14/7 be 0?

Answer 9

oh it =2

Answer 10

if you work out the negative signs you'll get (8+6)/(-4+3) = ?

Answer 11

oh i did the opposite

Answer 12

yeah, it's 2, but 2 is not an option, which means that the first point mentioned is actually the second point in the formula

Answer 13

what does that mean?

Answer 14

(-4,8)= (x2, y2)

Answer 15

(-3,-6)=(x1, y1)

if the slope formula = (y2 - y1) / (x2 - x1) then you just plug in the numbers, and simplify the negative signs...
+ times - = -
- times - = +
+ times + = +

Answer 16

i got 0

Answer 17

you can't have 0 as a result from a division, unless the nominator is 0

Answer 18

hum

Answer 19

\[slope = \frac{ y _{2} - y _{1} }{ x _{2}-x _{1} }\]
\[slope = \frac{ 8 - (-6) }{ -4-(-3) }\]
\[slope = \frac{ 8 + 6 }{ -4+ 3 }\]

you first add up what is in the numenator, secondly you add up what is in the denominator, and then you divided those 2 results which is?

Answer 20

so it 14 thats what i got

Answer 21

14/(-1) = -14 ;-)

Answer 22

-4 + 3 = -1

when you divide by -1 it's like dividing by 1, but you change the sign from positive to -
