Answer:
slope: 1; y-intercept: 3
Explanation:
The y-intercept is the y-value where the graph crosses the vertical y-axis. That value is 3.
The slope is the "rise" divided by the "run" for the graph. Here, the graph goes up 1 unit for each unit to the right, so the slope is ...
m = rise/run = 1/1 = 1
The slope is 1, and the y-intercept is 3.
