Question

Write an equation in point-slope form for the line through the given point with the given slope.
(8,3); m=6

Answer 1

y+3=6(x-8)
y-3=6(x-8)
y-3=6(x+8)
y+3=6x+8

Answer 2

point-slope formula : y - y1 = m(x - x1)
slope(m) = 6
(8,3) x1 = 8 and y1 = 3
now we sub
y - 3 = 6(x - 8)

any questions ?

Answer 3

Oh wow that was easier than I thought it would be. Thanks, no questions. :) I just need to remember the formulas.

Answer 4

lol....there is so many formulas.....I don't remember them all

Answer 5

So basically for every question like this one, you just take the formula and replace the variables with the info from the question to get the answer?

Answer 6

yep...if they want point slope form. Just be careful for the signs.
For instance, if your points were (-8,3) and the slope of 6
your answer would be :
y - y1 = m(x - x1)
y - 3 = 6(x - (-8)
y - 3 = 6(x + 8)
understand ?

Answer 7

Yes, I understand. Thanks for all the help :)

Answer 8

anytime :)
