Answer: The equation is y= 1/3x-5
Step-by-step explanation: This is because y-intercept form is y=mx+b with m as the slope and b as the y-intercept. According to the graph, the y-intercept is -5. You can look at the points (0,-5) and (6,-3). The slope is change of y / change of x. -3 - -5 is 2. 6-0 is 6. Therefore, the slope is 2/6 or 1/3. Hence, the equation is y=1/3x-5
