Given:

The equation of a linear function is:


y=-(2)/(3)x-1

To find:

The y-intercept and slope of the given equation, then draw the graph of the equation.

Solution:

Slope intercept form of a line is:


y=mx+b ...(i)

Where, m is the slope and b is the y-intercept

We have,


y=-(2)/(3)x-1 ...(ii)

On comparing (i) and (ii), we get


m=-(2)/(3)


b=-1

Therefore, the y-intercept is -1 and the slope of the line is
-(2)/(3).

It means the graph intersect the y-axis at point (0,-1) and having slope
-(2)/(3). So, the graph of the equation is shown below.
