Question

Can someone check my answers real quickly?

A line passes through the point (4,-3) and has slope m=1. Find the equation in point-slope form.

A. y - 4 = x - 3

B. y + 3 = x + 4

C. y + 4 = x - 3

D. y + 3 = x - 4 <-- My answer, is this correct?

(Point-slope form is y-y1=m (x-x1)) I kinda think it might be, B as well but I'm unsure. Thanks :)

Oh! If it's wrong can you tell me what I did wrong?

Answer 1

y - y1 = m(x - x1)
(4,-3)...x1 = 4 and y1 = -3
slope(m) = 1

now we sub
y - (-3) = m(x - 4) =
y + 3 = m(x - 4)

you are correct...it is D

Answer 2

I should of just done that, I made it more complicated than it needed to be Lol. Thanks for the reassurance :)

Answer 3

no problem :)
