Answer:


Step-by-step explanation:

Answer:

Point-slope form:

y

−

4

=

−

2

(

x

+

3

)


Slope-intercept form:

y

=

−

2

x

−

2


Explanation:

Assuming you mean a line that passes through these two points, use point-slope form:

y

−

y

1

=

m

(

x

−

x

1

)


To find the slope, m, use the slope formula

m

=

y

2

−

y

1

x

2

−

x

1


(-3,4) and (1,-4):

m

=

−

4

−

4

1

+

3


m

=

−

8

4

=

−

2


Now, plug in the slope and either point into point-slope form:

y

−

4

=

−

2

(

x

+

3

)


To convert this to slope intercept form, isolate y and simplify:

y

−

4

=

−

2

x

−

6


y

=

−

2

x

−

2

I have the other two answers. i just need the maximum height. please
Alex777 [14]

You have the maximum height happens at 5 seconds.

Replace t with 5 and solve for h(t):

h(5) = -0.2(5)^2 + 2(5)

h(5) = -0.2(25) + 10

h(5) = -5+10

h(5) = 5

The maximum height is 5 feet.
