Answer 1

General Form

Question 2

What form is this equation?
y=4X-3

Answer 2

Slope-Intercept Form

Question 3

What form is this equation?
1.5x+3y=-1.5

Answer 3

Incorrect formatting

Question 4

What form is this equation?
2y=2x+3

Answer 4

Incorrect formatting, however can become y=4x+6 (divide all by 2)

Question 5

How to find distance between two points?

Answer 5

“Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points. Created by Sal Khan and CK-12 Foundation.”

Question 6

What is the distance formula?

Answer 6

D=√((x2-x1)²+(y2-y1)²)

Question 7

How do you times an amount by a percentage (of itself)?

Answer 7

Use decimals. E.g.
20% of 100
100 x 0.2

145% of 50
50 x 1.45

Question 8

What is a commission?

Answer 8

You receive a percentage of what you contribute/make. For example, a car salesman who sells 10 cars a week gets a % of those sales, same with a salesman who sells 30 cars per week. The better you do personally, the more you make (but still only a percentage).

Question 9

What is a royalty?

Answer 9

You receive a percentage of total sales. E.g writers in Australia get 15% of a hardcover book sold. This is different from commissions as the writers get this percentage no matter what they contribute, as long as the total sales happens they get the %.

Question 10

What form is this equation?
y − 6 = 0.5(x − 8)

Answer 10

Point-Slope Form (good job)
