Part 1: Write the equation of the line that passes through the points (–1, –4) and (2, 5).

Part 2: Using complete sentences, explain whether or not it matters which point is used in the final answer. Also explain why you chose the point you did.

Part 1: Write the equation of the line that passes through the points (–1, –4) and (2, 5).

Part 2: Using complete sentences, explain whether or not it matters which point is used in the final answer. Also explain why you chose the point you did.

anonymous · Answer

i know the slope is 3
so when you put it in point slope form it would be : y = 3x - 1

anonymous · Answer

thats where i stopped. If someone could help me finish, that would be greatly appriciated.

ganeshie8 · Answer

thats correct equation. you finished the whole question in one line !!!

anonymous · Answer

:D THANKS! but how do i , explain whether or not it matters which point is used in the final answer

ganeshie8 · Answer

you found slope by using hte slope formula, right ?

ganeshie8 · Answer

and substituted it in the equation, 

y = mx + c

ganeshie8 · Answer

y = 3x + c

ganeshie8 · Answer

not how did you find "c" ?

anonymous · Answer

y + 4 = 3x = 3
subtract 4 from both sides.

doesnt -1 = c?

ganeshie8 · Answer

hmm i didnt get how you put first line
