Which one's contain the points?

Question

Choose the equation(s) whose line contains the point (-5,4)

. Check all that apply.

1. y=2x+6
2. y=-5x
3. 4x=7
4. 3y=9
5. y=1/2x-1
6. x=5y=-3
7. -6x+6y=-17
8. 3x+3y=17

If you could let me know which one's are on the line that would be great! Thank you!

Answer 1

the point isn't on any of the equation's lines

the first one might have worked except the sign is wrong

y=2x+6. plug in the point (-5,4) and see if the equation is true. replace x by -5 and y by 4

4=2(-5)+6

4=-10+6

4 =-4

if would have been on the line if the equation had been

-y =2x+6, then

-(4)=2(-5)+6

-4 =-4

plug in the point into every other equation, the you never get an equality. the point isn't on any of the lines described by any of the equations
