What is the equation in point-slope form of the line passing through (1, 9) and (−1, 11)?

y + 9 = −(x − 1)

y − 9 = 1(x + 1)

y + 9 = 1(x + 1)

y − 9 = −(x − 1)

ok nevermind those.im half asleep

anonymous · Answer

point slope is y-y1=m(x-x1)

anonymous · Answer

am i right @skullpatrol

skullpatrol · Answer

$$\huge  y-y_1=m(x-x_1)$$

anonymous · Answer

first you need to find the slope

anonymous · Answer

so what is the slope of the line @BIZZLE05

skullpatrol · Answer

The formula is right @marinesrock but I prefer the student to ask MORE questions :)

anonymous · Answer

This is the formula for that

skullpatrol · Answer

Without the student putting in effort to ask questions, no amount of teaching will help.

anonymous · Answer

ur right @skullpatrol i will stand by and if he makes a mistake i will point it out

anonymous · Answer

i don't know it, that's why i asked the question

anonymous · Answer

ok make a graph and graph the points.

skullpatrol · Answer

That @BIZZLE05  is not a question, it's request for the answer.

skullpatrol · Answer

What makes math so hard is that to understand it you have to do it yourself.
