Question 1

linear equation standard form

Answer 1

Ax + By

Question 2

linear equation slope intercept form

Answer 2

y = mx + b

Question 3

linear equation point slope form

Answer 3

y - y1 = m(x - x1)

Question 4

linear equation 2 point form

Answer 4

y - y1/x - x1 = y2 - y1/x2 - x1

Question 5

intercept form

Answer 5

x/x1 + y/y1 = 1

Question 6

flipping inequality signs

Answer 6

x + 2 > 2x - 3 is the same as 2x - 3 < x + 2
- if we multiply or divided both sides of the inequality by a negative number then the inequality is flipped
- only for multiplication and division and only with negative numbers

Question 7

y and x coordinate

Answer 7

• if the y coordinate is the same for two points on a line then the slope is 0 and the line is horizontal
• if the x coordinate are the same for two points on a line, there is no slope and the line is a vertical line

Question 8

perpendicular lines

Answer 8

have slopes that are negative reciprocals to each other, such as a/b and -b/a

Question 9

maximum possible error

Answer 9

+ or - half of the smallest unit
- for example if the unit measurement is 1 centimeter the maximum possible error is 1/2 centimeter
