<h3>Answer:</h3>
In this question, it's asking you to find how much percentage the circle graph is for "A" papers.
To solve this question, we would need to use information from the question.
Important information:
- Graded 50 English research papers
- 12 of those papers had an "A" grade
With the information above, we can solve the question.
We know that there are 12 research papers that received an A and there are 50 research papers in total.
We would divide 12 by 50 in order to find the percentage of the papers that got an A.
When you divide, you should get 24.
This means that 24% of the circle graph is devoted to "A" papers.

○ 3
○ y + ½ = 3(x - 2)
○ Multiply both sides of the equation by 3. The Standard Form of the equation is 12x - 2y = 24.
○ 5x - 3y = 15
○ y = ½x + 5⁄2
Step-by-step explanation:
Find the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m → (-1, 1) and (-2, -2)
__________________________________________________________
According to the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em>, all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting this coordinate into the formula with their CORRECT SIGNS:
(2, -½) → y + ½ = 3(x - 2)
__________________________________________________________
We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it:
-3[4x - ⅔y = 8] → -12x + 2y = -24
** They should have multiplied by -3 instead of 3 because that negative is hooked up to everything in the fraction, but since the exercise gave you 12x - 2y = 24, go with 12x - 2y = 24.

If you would take a look at this graph real closely, you will see that this graph intersects the y-axis and x-axis at ENDPOINTS, so to find the x-intercept, you simply plug in <em>zero</em> for <em>y</em>: 5x = 15, and you will know right away that <em>x</em><em> </em>is set to equal 3, which is what you see in the graph, (3, 0). Now, to find the y-intercept, you simply plug in <em>zero</em><em> </em>for <em>x</em>: -3y = 15, and you will know right away that <em>y</em><em> </em>is set to equal -5, which is what you see on the graph as well, (0, -5). With that being said, you have your answer.
__________________________________________________________
y - 3 = ½(x - 1)
y - 3 = ½x - ½
+ 3 + 3
_____________
y = ½x + 2½
* 2½ = 5⁄2
