1. sector. If you draw it out, it is like a slice of a pie. When you think sector, think section.

2. A 60 degree sector is 1/6 of a circle which is 360 degrees. So the area is 1/6 * 42 = 7, so B

3. area = pi * r^2 = 3.14 * 3^2 = 28.27, which is closest to A

Use the expression for the slope from part B to write a general equation for the slope of any two points (a, b) and (c, d).

Dmitrij [34]

Using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).

<em><u>Recall:</u></em>

Given the slope (m) of a line, we can write an equation in point-slope form of the line can be written if we know one of the points as, $y - y_1 = m(x - x_1)$ , where $(x_1, y_1)$ is a point on the line and m = slope.

From the question given, the slope gotten from part B is missing in this question. However, let's assume the slope (m) = 3.

Using one of the points, say (a, b), to write a general equation in point slope form, substitute $(x_1, y_1)$ = (a, b) and m = 3 into $y - y_1 = m(x - x_1)$ .

Thus:

$\mathbf{y - b = 3(x - a)}$

Therefore, using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).
