Math

Question 1

Distance formula : d= the square root of (x1-x2) squared + (y1-y2) squared

Answer 1

This is used to find the distance between two points on a rectangular coordinate system when solved simplify the root answer at the end

Question 2

Midpoint formula ( x1+x2)/2 , (y1+y2)/2

Answer 2

This is used to find the middle point between two points
First you solve the top of the fractions then divide by two or simplify the fractions that will give you the midpoint

Question 3

X - intercept

Answer 3

When the line crosses the x axis on the graph

Question 4

Y - intercept

Answer 4

Where the line crosses the y axis on the graph

Question 5

Slope formula: y2-y1/x2-x1

Answer 5

Slope is the rate of change between two points
The y’s are the change of height and ten x’s are the change of length

Question 6

Standard form: Ax+ By=C

Answer 6

This is used when you want to determine the y and x intercepts

Question 7

Slope intercept form: y = Mx + b

Answer 7

This is the easiest way to determine the slope of a line
M= slope
B= y intercept

Question 8

Point slope form: (y-y1)=m(x-x1)

Answer 8

This is used when you want to determine an equation of the line when you are only given the slope and a point of the line

Question 9

What is different about the perpendicular slop?

Answer 9

It used the negative reciprocal of the original slope

Question 10

What is the slope when the line is vertical and only intercepts the x axis

Answer 10

Undefined
