(3,13) and (6,14) <br> Rate of change and initial value???<br> Please help me

andriy [413]

Answer:

Part 1) The rate of change is $\frac{1}{3}$

Part 2) The initial value is $12$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

(3,13) and (6,14)

substitute the values in the formula

$m=\frac{14-13}{6-3}$

$m=\frac{1}{3}$

therefore

The rate of change is $\frac{1}{3}$

step 2

Find the initial value

we have

$m=\frac{1}{3}$

$point\ (3,13)$

substitute in the equation $y=mx+b$

$13=\frac{1}{3}(3)+b$

solve for b

$13=1+b$

$b=13-1=12$ ---> initial value

The linear equation is equal to

$y=\frac{1}{3}x+12$

The y-intercept or initial value is 12

Two skateboarders start a race at the same time skateboarder A travels at a steady rate of 15 feet per second skateboarder B tra

Dmitriy789 [7]

Answer:

Step-by-step explanation:

Relative speed can play a major role in creating distance between two bodies. If the relative speed between two bodies is 0, then both the bodies are moving in the same direction with a similar speed. Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.

Skateboarder A travels at a steady rate of 15 feet per second.

Skateboarder B travels at a steady rate of 22 feet per second.

We need to determine that after 4 minutes, how much farther will Skateboarder B have traveled.

The formula for finding the distance travelled by anybody is represented below

Time is given that is 4 minutes which means 240 seconds.

Thus,

Distance travelled by skateboarder A

Distance travelled by skateboarder B.

Therefore, the separation of the distance between both the skateboarders is 5280 - 3600 = 1680.

Thus, After 4 minutes, 1680 feet farther will Skateboarder B have traveled.

Write in equation passing through the point that is parallel to (8,3); y=-1/4x+7

BaLLatris [955]

Answer:

y=-1/4x+5

Step-by-step explanation:

Use the point-slope form which is y-y1=m(x-x1) where m is the slope. In this case, y is equal to 3, and x is equal to 8, and the slope is equal to -1/4. Therefore, the equation will be equal to y-3=-1/4(x-8). Simplify that to get y-3=-1/4x+2. Simplify this again to get y=-1/4x+5. Therefore, the equation is y=-1/4x+5.
