Answer:
14/15
Step-by-step explanation:
1. Convert the fractions to have the same denominator
Remember that you can only add fractions with the same denominator
To find the common denominator, find the LCM of 5 and 3 which is 15.
-2/5 * 3/3 = -6/15 and 4/3 * 5/5 = 20/15
-6/15 + 20/15 = 14/15

When a question is asking you for the y-intercept based on a graph, all you have to do is look to see at what point does the function cross/intersect the y-axis. The x-value will always be zero in a y-intercept. By looking at the graph you see that the function crosses the y-axis at the point (0, -1), which is your answer.
