Question

I think I'm doing these equations right, I just want to double check?
1. Write the equation of a line in point-slope form that has a slope of 1/3 and passes through the point
(-6, 0).

2.Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

Answer 1

what did you get?

Answer 2

for the first one i got y - 0 = 1/3 (x -6)

Answer 3

y - 1 = -2(x - 5)

Answer 4

you need to be careful when you subtract a negative number... you have a couple of errors above.

subtracting -1 from y gives you y - (-1) which is really y + 1

Does that make sense?

Answer 5

you are on the right track, but you have to be careful:
first one slope of 1/3 and passes through the point (-6, 0).

y-0 = (1/3)(x - (-6))
y= 1/3 (x+6) notice - -6 is +6. And we can leave out the -0 in y-0


second one
slope of -2 and passes through (5, -1).
y - -1= -2(x - 5)
simplify using - -1= +1
y+1= -2(x-5)
