Answer:
y=-1/4x-6
Explanation:
Y-intercept is -6 because that is where the line touches on the y-axis. For slope, pick two points and remember rise over run.
Pick (0,-6) and (4,-7) for example. Referencing the graph, from -6, count over and down until you get to (4,-7). The line represents a negative slope, so your slope is -1/4
