The equation of a line passing through a point (x1,y1) and having a slope m is given by: (y-y1) = m(x-x1) Here x1 = -3 , y = 7 and m = -1/5 Substitute the values and you get the equation...

yes so the first terms are obviously y=-1/5 but i'm not sure what the last term is

|dw:1437750495600:dw| can you simplify this??

so is it 32/5 or 22
midhun.madhu1987
  • midhun.madhu1987
You will get an equation in x and y...

  • midhun.madhu1987
Just apply distributive property on both sides of the equation

so 22?

Do you know what distributive property is?

yes

  • midhun.madhu1987
so what will 5(y-7) = ?
anonymous
  • anonymous
5y-35

and what about the right side?

-1x-3
midhun.madhu1987
  • midhun.madhu1987
yes.. so 5y - 35 = -x - 3 5y = -x - 3 + 35 5y = -x + 32 so y = ??

y=-1/5x+32/5
