y = -3x-3 is a straight line of slope -3 intercepting the y axis at (0, -3) and the x axis at (-1, 0)

Explanation:

To find the intercept with the y axis, substitute x=0 into the equation of the line to find:

y = -3*0-3 = -3

So the y intercept is at (0, -3)

To find the intercept with the x axis, substitute y=0 into the equation of the line to find:

0 = -3x-3

Add 3x to both sides to get:

3x = -3

Divide both sides by 3 to get:

x = -1

So the x intercept is at (-1, 0)
