Answer:
A) parallel
It has the same slope.
y-intercept is 6.
So,
m = -5
b = + 6
y = -5x + 6
B) perpendicular
It has a negative reciprocal of the slope.
-5 = 1/5
y-intercept is 6
m = 1/5
b = + 6
y = 1/5x + 6

Believe its 3 sorry if its wrong
The dot product of the two vectors will be given as follows:
v*w=(-7i+4j)*(-6i+5j)
=(-7*(-6))i+(4*5)j
=-42i+20j
Hence the answer is:
v*w=(-42i+20j)
