Final answer:
To plot -10 and 3.5 on the number line, draw a horizontal line and mark zero. To the left of zero are negative numbers and to the right are positive ones. Count 10 units to the left of zero for -10 and 3.5 units to the right of zero for 3(1)/(2).
Step-by-step explanation:
To plot -10 and 3.5 (also written as 3(1)/(2)) on the number line, you'll need to remember that the number line represents all real numbers and it has a zero point (usually in the middle), negative numbers to the left of zero and positive numbers to the right.
Step 1:
Draw a straight horizontal line. This will be your number line.
Step 2:
Mark a spot on your line for zero (0). Then, make equidistant marks on both sides of zero. Each mark represents a number. To the left, they decrease in value (-1, -2, -3 etc.) and to the right, they increase in value (1, 2, 3 etc.)
Step 3:
To plot -10, count 10 units to the left of zero and put a dot at the 10th unit. This represents -10.
Step 4:
To plot 3.5, count 3 and a half units to the right of zero and put a dot at that point.
Now you have successfully plotted -10 and 3.5 on the number line.
