Does (-1,8) make the equation y= -8x true?

Question: Does (-1,8) make the equation y= -8x true?

Yes!

Explanation: You just need to plug in the values. The equation is y = -8x and we want to know if (-1, 8) is a point on the line. So, you take (-1, 8) and plug it into the equation. 8 = -8(-1)

A negative times a negative equals a positive. So -8*-1 = 8

(-1, 8) would make the equation true.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
