Parallel lines have the same slope, so since you want a line that is parallel to a line with slope -8, your line will also have slope -8.
The slope-intercept form of the equation of a line is
y = mx + b
where m is the slope, and b is the y-intercept.
You already know you have a slope of -8, so m = -8, and you have
y = -8x + b
Now you need to find the value of b.
Use the point you know and substitute it in for x and y, and solve for b.
y = -8x + b
Use x = -8, and y = 2.
2 = -8(-8) + b
2 = 64 + b
-62 = b
b = -62
Now replace b with -62.
y = -8x + b
y = -8x - 62
Abc would be the same order with Def so the coordinate to f is C

24 units ²
Step-by-step explanation:
In this problem, we are given the circumference of a triangle (after finding the perimeter) and want to find the area of a circle with that circumference. Since the area of a circle is a function based on its radius, we can use the circumference to find the radius to find the area.
First, we can figure out the perimeter of the triangle, which is equal to the sum of its sides. The perimeter is 6+4+7.21 = 17.21 units.
Next, the circumference of a circle is equal to π * diameter = π * 2 * radius. Using 3.14 for π and r for radius, we get
3.14 * 2 * r = 17.21
6.28 * r = 17.21
divide both sides by 6.28 to isolate r
r ≈ 2.74
Furthermore, to find the area from the radius, we can use
area = πr². Plugging 2.74 in for r, we get
2.74² * 3.14 = area
≈23.6, rounding up to 24 units ²
