Identifying Slope and Y-Intercept from Linear Equations

What is the y-intercept of a graph?

• The point where the graph crosses the x-axis

• The lowest point on the graph

• The point where the graph crosses the y-axis

• The highest point on the graph

How is the y-intercept written as a point?

• (y, 0)

• (0, y)

• (y, x)

• (x, y)
