Question

what is the slope and y-intercept of this line?
y= -2x +8

a.) slope: 8, y - intercept: -2
b.)slope: 2,y - intercept: -8
c.)slope:-1,y-intercept: 4
d.)slope:-2,y-intercept:8

Answer 1

@Vocaloid please help

Answer 2

@Hero help?

Answer 3

\[y=mx+b\]where\[y=vertical~axis\]\[x=horizontal~axis\]\[m=slope\]\[b=y-intercept\]

Answer 4

compare\[y=-2x+8\]with\[y=mx+b\]

Answer 5

how? @MARC_ and thank you for the help

Answer 6

ohh i get it now, thanks for the help!! @MARC_

Answer 7

could you help with this one,
y = x - 5

Answer 8

i think its slope -5 and intercept 1 but im not sure :(

Answer 9

give u a hint
\[y=1x-5\]

Answer 10

ohh so its slope - 1 and 5 intercept?

Answer 11

how u get -1 for slope?

Answer 12

umm I divided 1/5 i dont know. /(T.T)/

Answer 13

use this equation y=1x-5 and try comparing with y=mx+b

Answer 14

so would I multiply? 1 x 5?

Answer 15

u do not need to multiply but u just need to compare only

Answer 16

how would one do so?

Answer 17

b gives u -5 when u compare with y=mx+b with y=1x-5
now m gives u what? (try comparing it)

Answer 18

b gives me 1x?

Answer 19

no

Answer 20

no
y=mx+b where
y=vertical axis
x=horizontal axis
m=slope
b=y-intercept

Answer 21

m=1 @amina_soneviseth

Answer 22

Therefore,the slope is 1 and the y-intercept is -5
