When you change a slope from positive to negative, it flips because it goes from being an increasing slope to a decreasing slope. negative slopes decrease as they move from left to right; positive slopes increase from left to right. in the case of y = x, which is line directly through the origin, this line is steadily increasing from the bottom left corner to the top of the right corner of a graph. when you change the slope from 1 to -1, the graph instead declines from the top left to the bottom right.

When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88

Natali5045456 [20]

Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!

Three times a number plus twice another is 10, while their sum is 10, Find the numbers

Aleks [24]

$3a+2b=10 \\\\ a+b=10 \\\\ \boxed{a=10-b} \\\\ 3(10-b)+2b=10 \\\\ 30-3b+b=10 \\\\ -b=10-30 \\\\ -b=-20 \\\\ \boxed{b=20} \\\\ a=10-20 \\\\ \boxed{a=-10}$
