With this revision of the Lial Developmental Algebra Series, the team has further refined the presentation and exercises throughout the text.

MyMathLab is not a self-paced technology and should only be purchased when required by an instructor. The expression is still not in factored form because it is the sum of two terms. This does not lead to a common factor, so we try rearranging the terms. Trial and error suggests the following grouping. Since the quantities in parentheses in the second step must be the same, we factored out?

Check by multiplying. Now write the percent in decimal form. Coordinates of the points shown are integers. Identify the quadrant in which the point is located. In each case, we begin at the origin. Step 1 Move right or left the number of units that corresponds to the x -coordinate in the ordered pair— right if the x-coordinate is positive or left if the x-coordinate is negative. Step 2 Then turn and move up or down the number of units that corresponds to the y -coordinate in the ordered pair— up if the y-coordinate is positive or down if the y-coordinate is negative.

The order of the coordinates is important. The x-coordinate is always given first in an ordered pair. To plot the point, think of the improper fraction as the mixed number and move units to the right along the x -axis.

Then turn and go 2 units up, parallel to the y -axis. The point 4,? The point 5, 0 lies on the x -axis because the y -coordinate is 0. The point 0,? The point 0, 0 is at the origin. Points on the axes themselves are not in any quadrant.

D The figure at the right shows a line that has a positive slope because it rises from left to right and a positive y-value for the y-intercept because it intersects the y-axis above the origin.

For each line in Exercises, decide whether a the slope is positive, negative, or zero and b the y-value of the y-intercept is positive, negative, or zero. Find the product. Use the FOIL method. See Examples
