Question

A line has a slope of –3 and passes through the point (4, –3).


Which is the equation of the line?


Question 2 options:

y = –3x – 15

y = –3x – 9

y = –3x + 9

y = –3x + 15

Answer 1

Use the formula :(y-y1)=m(x-x1)
here y1=-3 x1=4 and m=-3=slope

Answer 2

im confused?

Answer 3

Plug your values into the formula. y-(-3)=-3(x-4)

Answer 4

So its B?

Answer 5

So you have y+3=-3x+12
Move the 3 over so you have y=-3x+9

Answer 6

Oh okay!

Answer 7

equation of a line whose slope m=-3 and passing through the point(x1,y1) =(4,-3)
is

Answer 8

Thank you!

Answer 9

No problem.
