Answer:
The slope of this line in y = mx + b format is y = -x + 50
Explanation:
This line is negative, which means the slope (m) will be negative. B is the y-intercept, or where the line hits the y-axis. In this case, we can see that it's 50. Slope is rise over run, so -1/1. This can be simplified to -1. We don't write 1 in front of variables because it's unecessary, so the final answer is
y = -x + 50
