Find the slope and the y-intercept.
f(x) = -6x -9
The slope is ?.
The y-intercept is (0, ?)
Solution:-
Standard form of line is y = mx + c
Where m = slope
Compare the given equation by main equation of line
Slope m = -6
For y-intercept put x=0 in given equation
Y= -6*0 – 9
Y= -9
So y-intercept (0,-9)
