Question

What is the slope of the line 2x + 5y = -10?

negative five halves

five halves

two fifths

negative two fifths

none of the above

Answer 1

@nubeer

Answer 2

make x=0, what is y?
make x=1, what is y?

what is the change in y from x=0 to x=1?

Answer 3

1 is the change

Answer 4

no, it isnt

Answer 5

and idk bout the 1st 2 things

Answer 6

wut is it then?

Answer 7

Ax + By = C
y = -A/B x + C/B

-A/B is the slope

Answer 8

slope is the change in the value of y, as x changes by 1

Answer 9

2(0) + 5y = -10 , solve for y

2(1) + 5y = -10 , solve for y

what is the change in y, from x=0 to x=1?

Answer 10

uhhhm i would have to say c... i think..

Answer 11

oops i mean -2/5

Answer 12

(1) is the change?

Answer 13

when x=0

2(0) + 5y = -10 , solve for y

Answer 14

-5y on both

Answer 15

sides

Answer 16

2(0) + 5y = -10

5y = -10

5(-2) = -10 .... when x=0, y = -2

Answer 17

ohhh

Answer 18

when x=1

2(1) + 5y = -10

2 + 5y = -10

5y = -12

when x=1, y= -12/5

Answer 19

the change in y is therefore:
\[-\frac{12}5-(-2)\]
\[-\frac{12}5+\frac{10}5\]
\[\frac{-12+10}5\]
\[\frac{-2}5\]

Answer 20

yays i got it riight

Answer 21

Okie dokie thanks alot

Answer 22

it is important to know what slope IS, and then you can be able to work it into properties such as: ax+by = c, slope is -a/b

Answer 23

Oh i see
