The events 'select a plain pencil' and 'select a color pencil' are independent. therefore the probability of both occurring is the product of their probabilities:
The answer is 3/20 or 0.15.
The answer is 3/20 or 0.15.
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equations in the standard form. Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>
<em>add x to both sides</em>
<em>divide both sides by 3</em>

We need only two points to plot a graph of each function.
for x = 0 and for x = -3:
for x = 0 and for x = -3:
Look at the picture.
