Problem 460

 

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)
