Answer:

Step-by-step explanation:

<span>In getting the value of R in the formula of the circumference that you give where as the circumference is equals to 15, the derived formula is R=C/2pi and the answer would be that R is equals to 2.39. I hope you are satisfied with my answer and feel free to ask for more if you have more questions and further clarifications </span>
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have the points (-3, 1) and (2, -4). Substitute:

Therefore we have the equation of a line

Put the coordinates of the point (-3, 1) to the equation:

<em>subtract 3 from both sides</em>

<h3>Answer: y = -x - 2</h3>
