The answer is B. <span>{(1, 2), (2,4), (−1, 2), (0,3)} because it's the only answer where the variables for x aren't repeated. For example, x is 3 twice in A, x is 5 twice in C, and x is -4 twice in D. Please mark me Brainliest! :)</span>

Answer: 8

72π=226.19

226.19=π3^2h

226.19=π9h

226.19=28.27h

226.19/28.27=h

8=h

Plsss help me graph this!!! Attached is the question

The graph is a straight line graph with a slope of -1/2

Equation of a line in point-slope form

The equation of a line in point slope form is expressed as:

y - y₁ = m(x - x₁)

Given the following parameters

Point = (-2, 3)

Slope = -1/2

Substitute the given parameters into the formula

y-3 = -1/2(x-(-2))

y-3 = -1/2(x+2)

Write in slope-intercept form

2(y-3) = -(x+2)

2y-2(3) = -x -2

2y - 6 = -x -2

2y = -x + 4

y = -1/2x + 2

The graph of the equation is as shown below

Kai used fabric measuring 5 yards in length to make each costume for a school play. The relationship between the number of costu
Yuki888 [10]

The best interpretation of 2 in the given context is that; 2 represents the total length of fabric in yards purchased when no costumes were made.

<h3>Slope Intercept Form</h3>

We are given the relationship between the number of costumes that Kai made, x, and the total length of fabric that he purchased y, in yards as; y - 5x = 2

Where;

  • x is number of costumes made
  • y is total length of fabrics purchased.

Now, the general slope intercept form of an equation is given by; y = mx + c

Where c is the y-intercept which is the point where x is zero.

Thus, our equation can be rewritten as;

y = 5x + 2

Comparing with y = mx + c, we can say that c = 2

This means that at x = 0, y = 2.

In conclusion, the value 2 represents the length of yards purchased when no costumes were made.
