Answer:
Step-by-step explanation:
First we need to determine the equation of the boundary line.
The line has y-intercept of c=7 and slope .
The slope is given by y=mx+c.
We substitute the slope and intercept to get:
.
Since the lower half plane is shaded, with the boundary being a dashed line, the required inequality is
ANSWER
a) Orthogonal
b) Not orthogonal.
EXPLANATION
The given vectors are:
a)
and
If the dot product of two vectors is zero, then the two vectors are orthogonal.
These two vectors are orthogonal.
b)
The second pair of vectors are:
and
This pair is not orthogonal.
