Slope is rise over run
I would suggest writing the coordinate that is farthest to the left first so it is easier to visualize (-1,-6),(2,3)
as you go to the right, it goes over three, and up 9
9/3 simplifies to 3
the slope is 3
Answer:
b
Step-by-step explanation:
y=y
x+9 = 2x + 2
x-2x=-9+2
-x=-7
x=7
Answer:
y = 5x - 4
Step-by-step explanation:
Step 1: Write known variables
m = 5
y = 5x + b
Step 2: Find <em>b</em>
6 = 5(2) + b
6 = 10 + b
b = -4
Step 3: Rewrite equation
y = 5x - 4
Answer:
see the explanation
Step-by-step explanation:
we have the quadratic equation

This is a vertical parabola open downward
The vertex is a maximum
Find the x-intercepts of the quadratic equation
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0

Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula





therefore
This parabola has two x-intercepts representing the times when the dolphin's height above water is zero feet
Answer:

Step-by-step explanation:
We are given the two functions:

And we want to find:

We will find g(-2) first. So:

Thus:

Evaluate:

Therefore:
