find the slope and the y-intercept
f(x)=-10x-9
m = -10
when x = 0, y = -9
10/-9
To find the slope and the y-intercept of the function f(x) = -10x - 9, we can rewrite the function in slope-intercept form, which has the form y = mx + b, where m represents the slope, and b represents the y-intercept.
Given that the function is already in the form f(x) = -10x - 9, we can see that the coefficient of x (-10) represents the slope (m), and the constant term (-9) represents the y-intercept (b).
Therefore, the slope is -10, and the y-intercept is -9.
