Question

Write the standard form of the equation of each line passing through P with slope m.

P= (-5,2); m =3/1

Answer 1

well can you help me lol?

Answer 2

Use y-y1 = m (x-x1)
substitute values of m x1 and y1 and then write in
Ax + By + C = 0

Answer 3

can you please explain this step by step?

Answer 4

First we use the equation for a line passing through a given point i.e y-y1 = m (x-x1)
we are given m = 3/1 , (-5, 2) means x1= -5 and y1 = 2
substituting in above equation we get
3
y - 2 = ---- (x - (-5))
1

this gives y - 2 = 3 (x + 5)
y - 2 = 3x + 15
transposing terms on LHS to RHS
0 = 3x - y + 15 + 2
so finally we get
3x - y + 17 = 0

Answer 5

are you sure this is the right equation we are to use here?

Answer 6

i mean like formula?

Answer 7

@marissalovescats can you take a look at this???

Answer 8

You should get y=3x+17 for this one

Answer 9

ok so how did you convert his answer to this?

Answer 10

y-y1=m(x-x1)
