Question

Points M(1,-3) and N(-2,-15) lie on the graph of y=4x-7. Determine ALGEBRAICALLY whether each point is collinear with M and N. 
1. R(.5,-5)  2. S(-1,11)

amistre64 · Answer

they are only on the same line if they fit the equation

masterchief · Answer

It's asking to solve algebraically

amistre64 · Answer

then plug them into the equation

   y=4x-7

and see if they make a true or false statement

amistre64 · Answer

unless you know of a different "algebraically" method

masterchief · Answer

Oh for some reason I thought the first two points were not collinear with the graph sorry.

amistre64 · Answer

it says to do it using algebra, not graph  :)

masterchief · Answer

No I know, I just thought the points did not lie on the the graph.

masterchief · Answer

Like they were trying to confuse you :P
