Yes i'm ass shmoop er's here Another one for you
- 00:04
here's question line has an x intercept of negative for
- 00:08
an a y intercept of eight What is it's slow
- 00:16
Okay so time to rise up and run to the
- 00:19
solution way Have a slope to calculate All right Given
Full Transcript
- 00:23
two points the slope is the difference of the y
- 00:25
co ordinates divided by the difference of the x coordinates
- 00:29
Right The rise over the run or the y two
- 00:31
minus y wan over x to minus x one Okay
- 00:34
one problem though we don't have the coordinates yet finer
- 00:37
detail but we kind of do They're being sneaky and
- 00:39
x intercept is located on the x axis It intercepts
- 00:44
the x axis right there So it must have a
- 00:47
y coordinate of zero right it's going nowhere just inside
- 00:50
of that thing So x intercept of negative four has
- 00:53
the coordinates Negative for and then zero because the y
- 00:56
thing use zero similarly Ah why Intercept is located on
- 01:00
the y axis which means it is an x coordinate
- 01:03
of zero for second point zero come eight We'll plug
- 01:06
these coordinates into the slope equation there like this And
- 01:09
we got eight month zero over zero minus negative for
- 01:12
yes that's tricky So it's eight over four We simplify
- 01:15
it and line a has a slope of to for 00:01:18.488 --> [endTime] the answers as in we're done
