Need help asap!! (summer packet)

DiKsa [7]

Part A:

Function A:

Slope = (7-3)/(5-3) = 4/2 = 2

Equation:

y - 3 = 2(x - 3)

y - 3 = 2x - 6

y = 2x - 3

Funcion B:

(0, 3 ) and (-5, 0)

Slope = (3 - 0)/(0 + 5) = 3/5

y-intercept (0,3) so b = 3

Equation:

y = 3/5 x + 3

Function C:

y = 3x + 1

Part B:

Rate of change is the change in y over the change in x (rise/run). It's also the slope

Function A: rate of change = 2

Function B: rate of change = 3/5 (smallest)

Function C: rate of change = 3 (largest)

Order linear functions based on rate of change from least to greatest.

Function B: y = 3/5 x + 3

Function A: y = 2x - 3

Function C: y = 3x + 1

the two lines represent the amount of water, over time, in two tanks that are the same size. Which container is filling more qui

uranmaximum [27]

The missing figure is attached down

Answer:

Container A is filling more quickly

Step-by-step explanation:

<em>Let us explain the linear relation</em>

The linear equation is y = m x + b, where

m is the slope of the line which represents the rate of change (change in y/change in x)
b is the y-intercept which means the initial amount of y (at x = 0)

<em>If a line represents the amount of water over time, then it represents the rate of filling of the water</em>

∵ There are two containers A and B that have the same size

∵ The two lines represent the amount of water over time in

containers A and B

∴ The slopes of the lines represent the rat of water in the tanks

→ That means the greater slope represents the greater rate

∵ The greater the slope, the steeper the line

∴ The container that represented by the steeper the line is filling quickly

→ The line represents container A is steeper more than the line

represents container B

∴ Container A is filling more quickly
