Slope Formula : Change in y/Change in x =
y2-yi
x2-x1
; Rise/Run
Slope Intercept form: y = mx+b; m is slope and b is the y intercept
Point Slope form: y - y1 = m(x-x1); m is slope and xl yl is a point
Standard Form : Ax + By = C

I
Warm up
1. Evaluate:
a) 15 - 3 =
b) -7 -9 =
c) 8 - (-6) =
d) 5 - 9 =
e) -3 + 5 =
2. From the graph identify the coordinates of
Ok

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
