Answer 1

y = 3x

Explanation:

To find out what the equation is here, divide the y coordinate by the x coordinate of the point given (2, 6). Here divide 6 by 2. That would equal 3. That means that the y coordinate is 3 times as much as the x coordinate. As a result we can make the equation y = 3x out of what we now know.

Answer 2

Y=3x
The line x+4 would have a y Intercept of 4. The graph doesn’t show that. Y=6 would be parallel to the x axis. The graph doesn’t show that either. So the answer is y=3x
