The x-intercept is the point where the graph cuts the x-axis, and the y-intercept is the point where the graph cuts the y-axis.
The x-axis is the line y = 0 and the y-axis is the line x = 0. To find the intercept between each axis and our graph, we just need to evaluate our function at x = 0 and y = 0.
Calculating the x-intercept, we have
The x-intercept is (8, 0).
Calculating the y-intercept, we have
The y-intercept is (0, -2).
