Why is the grid in Example 1 a good way to<br> represent a percent?

Tems11 [23]

Answer:

percent means <u>per hundred </u>

Between the 100 squares, 60 of them are shaded

so you do 60/100

it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100

when you calculate percentage, you do the fraction x 100

so it's 60/100 = 0.6 x100 = 60%

hope that answers your question

Find the slope of a line that passes through the given points. Write your answer below.

12345 [234]

Just use the formula:
$slope(m) = \frac{y_2-y_1}{x_2-x_1}$

Then, plug in numbers:
$m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}$

And that would be your answer: 3/5 is the slope.
