the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b ) is a point on the line
y + 1 = (x + 5) is in this form
(a) with slope =
(b) point on the line = (- 5, - 1 ) = (a, b)
The area of the sector is 472.6 ft²
<h3>Area of a Sector</h3>
For finding the area of the sector, you need apply the formula:
, where:
r= radius
α= central angle
The question gives:
r= radius= 19 ft
α= central angle = 150°
Thus, the area of the sector will be:

Answer:
Step-by-step explanation:
Step 1. Find the slope (by using the slope-formula)
m = slope
Step 2. Write the equation (using the slope and the points)
Here's how to do it:
Slope-intercept Formula whrere m = slope and b = y-intercept
Plug in the slope into the Slope-intercept Formula
Find the y-intercept (b) by using a point and substituting their x and y values
Point: (3, 7)
Step 3. Write the equation in Slope-intercept form
The answer to your problem is a+6x+5.
