what does the m stand for in slope intercept form
m = slope
300
what is the formula to find slope?

what is the MAD of 54, 56, 56, 57, 58, 59 (round to the nearest tenth)?
1.3
400
1. what is median? (200 points)
2. how do you find it? (200 points)
1. the number in the middle of the data set
2. you put the numbers in order, least to the greatest. if there is a even amount of numbers, you add the 2 numbers in the middle then divide by 2.

what is one difference between a zero slope and an undefined slope?
1 difference: for undefined slope the 0 is the denominator and for a zero slope the 0 is the numerator
2. undefined slope is vertical and zero slope is horizontal
