Answer:
Step-by-step explanation:
Since we know the line goes through points
and
, we can construct a line in slope-intercept form

where
is the slope and
is the Y-intercept.
The slope can be found using the two points provided:



The line is now represented as

To solve for
, we can plug in one of the two points:




We know have our line:

To determine if the point
falls on this line, we just plug the numbers into the equation and see if it holds true:





This does not hold true, so the point is not on the line.
Answer:
Step-by-step explanation:
10^-5 is .00001, If it was 10^5 it would be 100,000, but since it is negative, you will have to "flip" it around. 0.1 is 10^-1 10^-2 is .01, 10^-3 is .001 etc...
Now .00001 * 7.1 is just .000071
:) hope this helped.
