Step-by-step explanation:

the slope = (0+15)/(-1-4)=15/(-5)= -3

the Equation :

y+15= -3(x-4)

or

y+15 = -3x+12

y +3x=12-15

3x + y = -3

so, the correct answer is II only

Answer:

y + 15 = -3(x - 4)        II only

Step-by-step explanation:

y2 - y1 / x2 - x1

0 - (-15) / -1 - 4

15 / -5

= -3

- Since the slope is -3, the answer can't be 1.

y + 15 = -3(x - 4)

Hello!

It tells you what to do in the question

First round all the numbers to the nearest whole number

2.20 = 2
2.34 = 2
2.7 = 3

Then it says to multiply all the numbers

2 * 2 * 3 = 12

Then it says to divide by 6

12 /  6 = 2

The answer is 2 cubic yards

Hope this helps!

What is the equation of the graph
AveGali [126]

Answer:

y = 2x^2 + 1

Step-by-step explanation:

The graph you see there is called a parabola. The general equation for the graph is as below

y = a*x^2 + b

To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.

To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!

3 = a * (1)^2 + 1\\2 = a

Awesome, we've found both values. And we can write the result.

y = 2x^2 + 1

I'll include a plotted graph with our equation just so you can verify it is indeed the same.
