Write the equation of a line in slope-intercept form that has a slope of -1/4 and passes through the point (8, -1)

Answer 1

@philo1234

Answer 2

Slope intercept form is y=mx+b, where m= slope and b is the y-intercept

Answer 3

\[y-(-1)=-\frac{ 1 }{ 4 }(x-8)\] point slope form now solve for y

Answer 4

Use the point-slope form: y-y1=m(x-x1), where y1=-1 and x1=8, m=-1/4

Answer 5

idk how to do tht?

Answer 6

just plug in the values that u got and then put y by itself on one side.

Answer 7

i still dnt get it?

Answer 8

y+1=-1/4(x-8), then solve for 'y'

Answer 9

y+1=-1/4(x-8)
-1

Answer 10

Solve for 'y' u know how to do that right?

Answer 11

no?

Answer 12

@philo1234 ????

Answer 13

I would suggest u get rid of the paretheses on the right hand side by multiplying each term in the paretheses by -1/4 . then subtract 1 from both sides

Answer 14

y+1=-1/4
-1 -1

Answer 15

now wat @philo1234

Answer 16

I know u r messing with me. I think u know what to do. But here it is anyways:
y+1 = -1/4x-8(-1/4)
y+1 = -1/4x+2
-1 -1
y = -1/4x+1

Answer 17

umm no i dont lol im just not smart 0.o
