We can substitute the x and y-intercepts into the equation to solve for a and b.
a=-4, b=5
Practice makes perfect
To solve for a and b, we can substitute the x and y-intercepts into the equation. Let's look at each situation individually.
Solve for a
To solve for a, we can substitute the x-intercept into the equation. We are given that the x-intercept is -10. Since the x-intercept occurs when the function crosses the x-axis, we know that the point is (-10,0).
To solve for b, we can substitute the y-intercept into the equation. We are given that the y-intercept is 8. Since the y-intercept occurs when the function crosses the y-axis, we know that the point is (0,8).
