Answer:

Step-by-step explanation:
Let the equation of the perpendicular line is,
y = mx + b
where m = slope of the line
b = y-intercept
From the graph, slope of the line passing through (0, -1) and (3, 1),
m' =
m' = 
m' = 
To get the slope (m) of this line we will use the property of perpendicular lines,
m × m' = (-1)
m ×
= -1
m = 
Equation of the perpendicular line will be,

x-intercept of the line is (-3) therefore, point on the line is (-3, 0)
0 = 
b = 
Equation of the line will be,

Answer:
y - 5 = 3(x - 4)
y - 5 = 3x - 12
y = 3x - 7
Step-by-step explanation:
Answer:
<EFD= 47.5°
<CFD=47.5°
Step-by-step explanation:
Seeing that 85° is already there and it would be an opposite angle to <BFC all you would have to do is subtract that 85° from 180° because that's the angle of a straight line. then when you get 95° you divide it by 2.
Answer:
c=18
Step-by-step explanation:
54 divided by 9 is 6
6 times 3 is 18
