Question

The slope of the line below is -4. Write the equation of the line in point-slope form, coordinates (1,2)

Answer 1

(x1,y1) = (1,2)
m=-4
point slope form is given by

(y-y1)=m(x-x1)

Answer 2

Ok so we have
y-y1=m(x-x1)
What's the M in this equation?

Answer 3

-4

Answer 4

k good and what's the x1 & y1?

Answer 5

y is 1 x is 2

Answer 6

close but actually other way around :) (x1,y1)= (1,2) = x1=1 & y1=2

Answer 7

Ok so now that we have that, can u try putting the numbers in the equation where they belong? :)

Answer 8

o ya lookd at it wrong

Answer 9

y-2=-4(x-1) is what i came up with

Answer 10

yep perfect! :) & yeah I thought u looked at it wrong or something lol, i knew u knew that :) Great job :D

Answer 11

it is - right not +

Answer 12

U mean -4 instead of 4? Yeah because in the problem they said slope is -4, we can't take off that negative sign that was already on it :)

Answer 13

alright il post in question in live feed
