Multiply 45 by 2/3 2/3 = 0.66666 so 45*0.6666 = 30
Answer:
I believe it would be (c)
600kb in 24 seconds to find out how many kbs per second divide by 24
600/24 is 25kb
The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b
Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8
Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
