Answer:
slope = -3; y intercept= -3
Explanation:
slope: to find slope you have to find rise/run. if you start from the point (0,-3), and go up 3(rise) and to the left, making it negative, 1(run), you'll get the slope 3/-1 which simplifies to -3.
y intercept: the y intercept is the y coordinate where the line crosses the y axis (the vertical line on the graph). This one crosses at the point (0, -3), so the y intercept would be -3.
