Answer:

y=-4x-7

Step-by-step explanation:

if you use the slope formula, y2-y1 over x2-x1 using any two points from the grid, you get a slope of -4.

if you use the slope intercept form, y=mx+b, and plug in y, m the slope, and x, you get -3=-4(-1)+b

if you solve that, you get -3=4+b

and if you isolate 4 by subtracing 4 from both sides, b=-7.

then you plug slope and y intercept into formula, and get y=-4x+b

Can you identify these numbers as rational or irrational. Please explain.<br><br> -√127 and 291.87
irina [24]
An irrational number/value is one you cannot express in terms of a ration, or a fraction, it cannot be written as fraction

now 291.87... is simple, two decimals, so you use two zeros at the botom and end up with \bf \cfrac{29187}{100} and boom, there you are, a fraction, nice and dandy

now, let's see the first one -√(127)  well, low and behold, 127 is a prime number, and and thus is has no two factors that'd serve as root, so, there's no rational root that'd give that, that makes it irrational

80 books to 64 books percent of change
Alecsey [184]

Answer:

-20%

Step-by-step explanation:

64 to 80⬇

((64 - 80 / 64)) × 100 = 25 %

Therefore, your answer would have to be: 25% since it increased

Or you can try going with this method as well

80 to 64 ⬇

((80 - 64 / 80 )) × 100 = -20%

Therefore, for that method your answer would be-20% because it decreased
