Answer:
-1
y = -x -2
1
y = x + 6
Step-by-step explanation:
Given line is y = - x - 4
We know that the equation of a line is of the form y = mx + c where m is the slope of the line and c is a constant
Now The slope of the given line is m = -1
We know that the slope of any line parallel to the given line is same the original one
Therefore the slope of the line parallel to the given line is -1
Given the point is ( -4 , 2 ) and slope is -1
We know that the equation of a line passing through the point (c , d) and slope m is
Here the equation is
y = -x -2
We know that if two lines with slopes m1 and m2 are perpendicular then m1m2 = -1
Here m1 = -1 then
m2 = 1
Given the point is ( -4 , 2 ) and slope is 1
We know that the equation of a line passing through the point (c , d) and slope m is
Here the equation is
y = x + 6

Answer:
Step-by-step explanation:
Vertical angles are congruent.
8x = 2x +30
6x = 30 . . . . . . subtract 2x
x = 5 . . . . . . . . divide by 6
__
60y -40 = 40y +20
20y = 60 . . . . add 40-40y
y = 3 . . . . . . . .divide by 20
_____
<em>Check</em>
The 'x' angles are 8x° = 8·5° = 40°.
The 'y' angles are (40y+20)° = (40·3+20)° = 140°.
The angles are supplementary, as they are supposed to be.
