Find the rate of change and initial value. Y=mx+b

1 answer:

Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24

Find the slope of the line through the points (6,16) and (−6,4)

MakcuM [25]

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

$m = \frac{4-16}{-6-6} \\m = \frac{-12}{-12} \\\\m = 1$

Therefore, the slope of the line is 1. In case if you want to know the equation.

$y=mx+b\\y=x+b\\4=-6+b\\4+6=b\\10=b\\$

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

$y=mx+b\\y=x+b\\16=6+b\\16-6=b\\10=b\\$

It's the same, you can use any orders given.

Overall, the slope is 1 and the equation is y=x+10

The timekeeper for a particular mile race uses a stopwatch to determine the finishing times of the racers. He then calculates th

insens350 [35]

Answer:

300 seconds = 5 minutes

Step-by-step explanation:

At first convert the time in minutes which is

5.75 * 60 = 345 seconds

No as the average is 345 seconds at starts from 45 so we subtract that time from 45 seconds

345-45 = 300 seconds (Mean)

So 300 seconds = 300/60 = 5 minutes

So the Accurate mean is 5 minutes

What is the value of p in the linear equation 24p + 12 – 18p = 10 + 2p – 6?

stira [4]

we have

$24p+12-18p=10+2p-6$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$24p-18p-2p=10-6-12$

Combine like terms

$4p=-8$

Divide by $4$ both sides

$4p/4=-8/4$

$p=-2$

therefore

<u>the answer is</u>

the value of p in the linear equation is $-2$

-4(x+1)+5=17 solve for x

ahrayia [7]

-4(x + 1) + 5 = 17

Distribute -4 inside the parentheses.

(-4x - 4) + 5 = 17

Combine like terms (-4 + 5).

-4x + 1 = 17

Subtract 1 from both sides.

-4x = 16

Divide both sides by -4.

x = -4
