Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F, G). Which of the following is the equation of Leo's line? y - F = - 1/3 (x - G)
y - G = - 1/3 (x - F)
y - G = -3 (x - F)
y - F = -3 (x - G)

the square root of what number? if you add that, then someone will probably answer the question.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
