Answer:
The answer to number 3 would be 6 on the number line, open circle, and then a line dashed to 42, and 4 on the number line, closed circle, and a closed line to 7.
The answer to number 4 would be -8 on the number line, open circle, and then a line dashed to 2, and 9, open circle closed line to 81.
M = -2
In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.
So 1/2 becomes negative, and 2/1 = 2
So the slope is -2
Mean is the adding all numbers together and dividing by the amount of numbers there are
for example: 95 + 85 + 90 = 270
270/3 = 90
