Answer:
Graph 1: Y-intercept = 4
Graph 2: Y-intercept = -4
Explanation:
On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis. What are intercepts? The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.
