we are given equation of line

Equation of perpendicular line:
Firstly , we will find slope of line

we can compare it with
y=mx+b
we get

we know that
slope of perpendicular line will be -1/m
so, slope is

It passes through point (-4,5)
so, we can use point slope form of line

we get
..........Answer
Equation of parallel line:
Firstly , we will find slope of line

we can compare it with
y=mx+b
we get

we know that
slope of parallel line always equal
so, slope is

It passes through point (-4,-5)
so, we can use point slope form of line

we get
............Answer
Answer: -8x
Step-by-step explanation: to get the answer you would multiply 4x and -2.
4x*-2= -8x
Answer:
54degrees
Step-by-step explanation:
From the given diagram;
2<P + 136 + 74 + 42 = 360 (sum of angle at a point is 360degrees)
2<P +252 = 360
2<P = 360 - 252
2<P = 108
<P = 108/2
<P = 54
Hence the measure of <P is 54degrees
the sample would be the number polled - 50,000
the population would be all college students
