Answer:

y = 15x

Step-by-step explanation:

The question asked,  what equation shows the line through the data points.  And it stated the equation needed to be in the form y = kx

Where

y represents the vertical axis

x represents the horizontal axis

k = constant

K is the constant interval and can be use to get the next points

y = kx

viewing the most visible points from the graph , let use the point where total saved is 90(y axis) and the time in weeks (x axis) is 6, the constant K can be gotten.

y = 90

x = 6

y = kx

90 = 6k

divide both sides by 6

k = 90/6

k = 15

Therefore,

y = 15x

Area of a Triangle
jek_recluse [69]

Answer:

3.51 (round to the nearest hundreds)

Step-by-step explanation:

PART A

slope of the line passing through AC : (6-1)/(1-2) = 5/-1 = -5

equation of the line passing through B and perpendicular to AC:

y-3 = 1/5(x-3)

y-3 = 1/5x -3/5

y = 1/5 x - 3/5 + 3

y = 1/5 x + (-3+15)/5

y = 1/5 x + 12/5

PART B

line that passes through the points A and C

y-1 = -5(x-2)

y = -5x+10 + 1

y = -5x + 11

Interception of the lines

y = 1/5x + 12/5

y = -5x + 11

-5x + 11 = 1/5x + 12/5

-25x +55 = x + 12

26x = 43

x = 43/26

y = -5(43/26) + 11

y= -215/26 + 11

y = (-215+286)/26 = 71/26

D (1.65, 2.73)

PART C

AC = \sqrt{(1-2)^2 + (6-1)^2} = \sqrt{1 + 25} = \sqrt{26} = 5,09902

BD = \sqrt{(3-1.65)^2 + (3-2.73)^2} = 1,376735

PART D

AREA = (5,09902 * 1.376735)/2 = 3,509999
