find the slope if it exists, of the line containing the pair of points. (1,3) and (7,-7) I know you have to do it like -7-3/7-7 and then I get -10/6 and then -1.66666666666667 what do i do to simplify it and write as the answer
then reduce -10/6 to lowest term.
okay and how do i do that . that is what i was asking?
look for a common factor of 10 and 6,,
for example if you have 6/4, 6 and 4 have a common factor of 2, thus you can factor out 2 from both:
2*3 / 2*2 = 3/2
like that. try it to -10/6 ~ :)
i still don't get it
hmm,, well try this one, what are the factors of 10?
5 and..?
what do you multiply by 5 to get 10?
right. 5 and 2 are the factors of 10 because
2 * 5 = 10
now, what are the factors of 6?
3 and 2?
is that right? then what do i do. What is the answer?
yes! that's right! :)
now, from the factors of 10 (which is 2 and 5) and factors of 6 (which is 2 and 3), what number is common?
set 1: 2 and 5
set 2: 2 and 3
what number is common from both set?
right~! :)
now, you can cancel out 2 from both since it is a common factor:
-10/6 = -(2 * 5)/(2 * 3) = -5/3
so there,, :)
