What is the slope of the line that passes through the points (-2, 2) and (-1, 7)?
To find the slope of the line passing through two points, we can use the formula:

slope = (y2 - y1) / (x2 - x1)

Using the points (-2, 2) and (-1, 7), we have:
x1 = -2, y1 = 2
x2 = -1, y2 = 7

slope = (7 - 2) / (-1 -(-2))
slope = 5 / 1
slope = 5

Therefore, the slope of the line that passes through the points (-2, 2) and (-1, 7) is 5.
Which of the following is an irrational number?
A. 3.7
B. 121 Square Root

D. 8 over 9 is a fraction which is a rational number.

Therefore, the irrational number in the list is C. 65 Square Root.
Write 75,000 in scientific notation.
To write 75,000 in scientific notation, we move the decimal point to have a number between 1 and 10, and then express it as the product of that number and a power of 10.

75,000 can be written as 7.5 x 10^4 in scientific notation.
Convert 3 over 4 percent to a decimal
To convert a percent to a decimal, you divide the percentage by 100.

3% in decimal form can be computed as:

3 / 100 = 0.03

Therefore, 3% written as a decimal is 0.03.
