Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Answer:
Area of given figure = 37.68 unit²
Step-by-step explanation:
Given:
Radius of given shape = 4 unit
Angle = 270°
Value of π = 3.14
Find:
Area of given figure
Computation:
Area of given figure = [Ф/360][πr²]
Area of given figure = [270/360][(3.14)(4)²]
Area of given figure = [0.75][(3.14)16]
Area of given figure = [0.75][50.24]
Area of given figure = 37.68 unit²
<span>Multiply both sides of the fraction
by 3.
3/4 = 9/12 </span>
