Parallel = same slope
Y = -3x + 7, the slope is -3
Slope intercept form: y = mx + b
Y = -3x + b
Plug in point (2,-4) and solve for b
-4 = -3(2) + b
-4 = -6 + b, b = 2
Solution: y = -3x + 2
The answer is D

What is the slope of the graph?

Nookie1986 [14]

Answer: The slope is $\frac{3}{5}$

Step-by-step explanation:

The slope of a line can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Observe the graph provided in the exercise.

You can notice that these two points are on the line:

$(2,3)$ and $(7,6)$

Then you can identify that:

$y_2=3\\y_1=6\\\\x_2=2\\x_1=7$

Knowing these coordinates, you can substitute values into the formula for calculate the slope.

Then, you get that the slope of the graph is:

$m=\frac{3-6}{2-7}\\\\m=\frac{-3}{-5}\\\\m=\frac{3}{5}$

1. Cylinder A, B, and C have the same radius but different heights. Put the cylinders in

natulia [17]

The order of volume from least to greatest is C, B and A.

Step-by-step explanation:

Given:

Three Cylinders namely A, B, and C with different heights have the same radius.

To Find:

Arrange the cylinders from least to greatest with respective to their volume.

Formula for volume of cylinder:

V= $\pi r^{2} h$

i.e V∝ h (for constant radius)

where,

r = radius of cylinder

h = height of cylinder

we see that Volume is directly proportional to height.

Consider, $h_{1}, h_{2},h_{3}$ are the heights of cylinder A,B,C respectively, such that;

$h_{1}$ > $h_{2}$ > $h_3}$

And, $V_{1}, V_{2},V_{3}$ are the volume of cylinder A,B,C respectively.

So the order of volume will also be,

$V_{1}$ > $V_{2}$ > $V_3}$

Marta’s fruit stand sold x oranges on Thursday and twice as many on Friday. All together, on both days, she sold 108. Which bar

Allushta [10]

Step-by-step explanation:

Thursday = x

Friday = 2x (Since thursday is x and she landed up selling twice the amount she did on thursday, friday would be 2x)

Thursday + Friday = 108

For this problem you would need to find the value of x so you would need to substitute x into the equation that was created for the oranges sold on both the days

Thursday + Friday = x+2x = 108

x +2x = 108

3x = 108

x = 108/3

x= 36

Since x is thursday, Marta sold 36 oranges on thursday

To find the amount of oranges sold on friday you would need to multiply x, which is 36, by 2

2x = 2(36) = 72

72 oranges were sold on friday

Hope this helps!!!

Step-by-step explanation:

We know that Frank has 2 gardens, one with y vegetable seeds and another with 3y + 8 vegetable seeds. If we are trying to find the total amount of seeds planted, we must add the 2 gardens together:

Garden 1: y

Garden 2: 3y + 8

Garden 1 + Garden 2 = Total veggie seeds

y + 3y + 8 = Total veggie seeds

Total veggie seeds = 4y + 8
