Write the equation of the line that passes through the points (3, 4) and (–3, –8) in point-slope form.

Question

dumbcow · Answer

first find slope
$$m = \frac{y2-y1}{x2-x1}$$
then you point-slope form
$$y-y1 = m(x-x1)$$

Thanks

dumbcow · Answer

your welcome
i can check your answer for you too if you want

anonymous · Answer

Sure

anonymous · Answer

i got 7/11 for finding the slope , am I right ?

dumbcow · Answer

no you should get 12/6  = 2
remember with any point x is 1st number, y is 2nd number

dumbcow · Answer

(3,4)  --> x1 = 3, y1 = 4
(-3,-8) --> x2 = -3, y2 =-8

does that help

anonymous · Answer

i have to explain whether or not it matters which point is used in the final answer. Also explain why you chose the point you did ..... i dont get that part

dumbcow · Answer

it doesn't matter what point you use

dumbcow · Answer

whatever you think looks nicer i guess :)

anonymous · Answer

y - 4 = 2 ( x - 3) ?
