determine whether (-5,1) is a solution of 9x-9y= -3
I said no am i correct?
solve by elimination mehtod. 2x+3y=4, 4x+6y=8 type as ordered pair, type N for no solution, I for many.
I chose I am I correct?
math(am i right) -
How did you determine that the answer was "no" to the first one?
BTW. you were right.
For the second, what happens if you multiply your first equation by 2 ?
- So how many lines are you intersecting by solving ?
- Wouldn't any point that works for the first also work for the second ?
- How many points are on the first line ?
