Answer:

the slope  is 4

Step-by-step explanation:

y+3=4(x-5)

This is in point slope form

y-y1=m(x-x1)

where (x1,y1) is a point on the line and m is the slope

The slope is 4 and a point on the line is (5,-3)

Write a linear equation with slope -1 and y intercept of 3
MatroZZZ [7]

Answer:

y = -x +3

Step-by-step explanation:

Think about the Y= mx + b

m = -1 so it's -x

b = 3, so it's +3

y intercept goes after the slope:

Y= Mx + B

Y = -x + 3

The height in feet is modelled by the function below, where the t is in
Sedaia [141]

The object reaches the lowest height at 5 seconds

<h3>How to determine the time?</h3>

The function is given as:

f(t) = -2t² +22t + 6

Differentiate the function

f'(t) = -4t +22

Set to 0

-4t +22 = 0

Subtract 22 from both sides

-4t = -22

Divide both sides by -4

t = 5.5


Remove decimal points

t = 5

Hence, the object reaches the lowest height at 5 seconds
