Answer:
Pairs (2,4), (4,8) and (5,10) makes the equation y=2x true
Step-by-step explanation:
By using the equation y=2x, eval the following points (gathered from the attached picture)
1. (2,4) which leaves us 4=2*2
2. (4,8) which leaves us 8=4*2
3. (5,10) which leaves us 10=5*2
All points from this graph satisfies the equation y=2x
6x^{2}+4x
Factor: 2x out of 6x^{2}
2x (3x) + 4x
Factor: 2x out of 4x
2x (3x) + 2x (2)
Factor: 2x out of 2x (3x) + 2x (2)
2x (3x + 2)
