Answer:
y= -7
Step-by-step explanation:
This line is a horizontal line.
Horizontal lines all have the same form of y=k (where k is the y-intercept of the horizontal line).
The y-intercept is the point where the line meets the y-axis (the vertical axis). For this line, the y-intercept is in between -6 and -8, making it: (0,-7) or just -7.
Let's return to the form for horizontal lines.
y= k
The y-intercept is -7. Substitute -7 in for k.
y= -7
The equation of the line is y= -7
