When the notation is 10^-# you always move whatever the number is to the left of the decimal place
When the notation is 10^+# you always move whatever the number is to the right of the decimal place
2.4 x 10^-4 = .00024
You move 4 units to the left of the decimal place
The standard notation will be .00024
a and b represent the slopes in the equations. Use the y-mx+b formula to realize this. M is the slope, a or b in this question. The lines both have positive slopes so B or C cannot be the answer. I cant see the image properly, but if the y int is at 0 then A is the answer, but if it is above 0 then D will be your answer.
I think the answer is a single data point.
