Find the x and y intercepts. explain what they mean.

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis
so
x intercept when y = 0 and y intercept when x = 0

first table: 
x intercept: (10, 0)
y intercept: (0, 10)

second table: 
x intercept: (50, 0)
y intercept: (0, 25)

third table: 
x intercept: (300, 0)
y intercept: (0, 1200)
