Pictograph, Bar Graph, Circle Graph, Line Graph, Stem-and-Leaf Plot, Box-and-Whisker Plot, Line Plot, and Scatter Plot. Hope this helps, I'm learning the same thing right now test tomorrow thanks for the practice!
By our very goofy system the circle constant
denotes half a circle,
. So the conversion factor from radians to degrees is

Calling the rightmost dot [1] and counting counterclockwise, that's dot [4].

That's dot [6]

That's dot [12]

That's dot [14]
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
Answer:
9
Step-by-step explanation:
13-9= 4
3b - a = 45
a = 2b + 40
Solve simultaneously.
3b - (2b + 40) = 45
3b - 2b - 40 = 45
b = 45 + 40
b = 95min (1 hour 35 min)
a = 2 (95) + 40
a = 230min ( 3 hour 50 min)
