Question

Find the slope of the line joining (-3,2) and (3,-8)

Answer 1

sorry, typo...
The slope of the line between two points\[ (x_1,y_1)\]and\[(x_2,y_2) \]is given by \[m={y_2-y_1\over x_2-x_1}\]

Answer 2

would it be -8-2 / 3-3 = -10/-6

Answer 3

almost, but be careful with the minus sign:\[m={y_2-y_1\over x_2-x_1}={-8-2\over3-(-3)}={-10\over6}={-5\over3}\]

Answer 4

thanks but how did we get -5/3

Answer 5

divide by 2?

Answer 6

yes, that is how the fraction simplifies

Answer 7

ohh ok thanks so much
