List m passes through the points ( -4,3) and (-4,7). what is the slope of the line that is perpendicular to line m ?

Check the picture below.

notice, this line, in black, is really just a vertical line, namely x = -4.

a perpendicular line to that, like the red line there, will be a horizontal line y = [some number].

recall a vertical line always has an undefined slope, whilst a horizontal line always has a slope of 0.

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
