Answer 1

y=-2x-4

Explanation:

1) In this equation, -4 is the y-intercept (which is the point in the graph when x is 0 and y is something.)

2) Then, you have to check if the graph also has a y-intercept of -4 (it does)

3) Find out what the slope of the graph is. In this case, it is -2

4) If the equation also has a slope of -2 and y-intercept of -4, then it represents the graph.

Hope this helps :)
