The Slope of lines parallel to line is 1/2 and the Slope of lines perpendicular to line is -2.
<h3>What is the equation of a straight line ?</h3>
An equation that can be written in the form of y = mx+c
where m is the slope of the line
and c is the intercept on y axis
The equation given in the question is
y=1/2x−7
in this the slope = 1/2
Intercept = -7
For parallel Lines
For a parallel line , the slope of the line is same
and is given by m = 1/2
For a perpendicular line
Slope will be equal to
-1/m
here -1/m = -2
Therefore the slope for perpendicular line is -2.

Answer:
A
Step-by-step explanation:
Use the equation y-y1=m(x-x1) and sub in the values of the provided information
Answer:
Line CDE is a straight line,
so 85°+70°=55°
180°-55°=25°
angle BDA=25°
25°+85°=110°
180°-110°=70°
angle CDF=70°
