Question

Write the equation of the line that contains the points (2, 2) and (-3, 12).

Here is part of the answer. Can you identify the missing part?

y = -2x + ?  i need to know what the number in the question mark

anonymous · Answer

plug in one of your ordered pairs for x and y in the equation you gave.. Solve for ""?" or b
2=-2(2)+b

solve for b

anonymous · Answer

how? o.o

anonymous · Answer

there is no b in the eqaution i gave you
i just need to find a number the missing part i guess

anonymous · Answer

You gave a "?" which I replaced with b... If you recall the equation for a line is y=mx+b; where x and y are given by your ordered pairs and m=-2

anonymous · Answer

ohhhhhhh thanks
but can you give me the answer? :D

anonymous · Answer

you should be able to solve for b with what I gave you.. It is not that hard.. I think you may just be being lazy :P
