Please helpp
Ok...
Alright just me one sec, thanks!:)
k
Write in point slope form an equation of the line through each pair of points (1,9) and (6,2)
cant help sorryyyyy
The answer is y - 9 = -7/5(x-1) just not sure how to get this answer
idk
Can you help @ganeshie8
@kewlgeek555
Do you know the pointe-slope formula?
It's y - y1 = m (x - x1)
Okay, great job. Did you know you needed the slope for that, but you don't have the slope! OMG! But I have the solution: \[SLOPE = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
You just need two points and hey - you have two points! The point more to the left is:\[(x _{1},y _{1})\]and the point more to the right is:\[(x _{2},y _{2})\]
So...try to solve this to get your slope:\[\frac{ 2-9 }{ 6-1 }\]
-7/5?
(or -1.4)
;]
Thanks!:) can you help with another? Write the equation of the line through each point. Use slope intercept form. (1, -1); parallel to y = 2/5x – 3
Ooh...ask me anything that doesn't have to do with "parallel" or "perpendicular" I am horrible with that. Sorry, I am not going to help you if I can't really help. @ganeshie8 @mathstudent55 @agent0smith @DebbieG can help you - SORRY. T_T
Thanks anyway!:)
Parallel means the lines have the same slope.
So the line has the same slope as the other one, then use this point (1, -1) and y - y1 = m(x - x1)
