unit 3

Question 1

slope

Answer 1

m= y2 - y1 / x2 - x1

Question 2

Slope-intercept form

Answer 2

Y=mx+b

Question 3

Point-slope form

Answer 3

Y - Y1 = m(x - x1)

Question 4

Distance formula

Answer 4

D = radical (x2 - x1) ^2 + (y2 - y1) ^2

Question 5

adding/subtracting radicals

Answer 5

add/subtract the value infront of the radicals
radicand stays the same

Question 6

perimeter on the coordinate plane

Answer 6

find the sum of the distance of all sides

Question 7

area on the coordinate plane

Answer 7

boxing in :
•find the area of the whole box
•find the distance of all sides of the triangle
•1/2(L•L) for the mini triangles outside of the big triangle
•subtract it all from the whole area

Question 8

Partition

Answer 8

Seperate or divide a line segment into smaller segments aka ratios

2:3 means the segment is divided into 5 equal sections

Question 9
