Y=x+3 and y=-x-5.Is the line parallel, perpendicular or neither?

1 answer:

8 0

Answer:

Perpendicular.

Step-by-step explanation:

For parallel lines slopes are equal.

The slope of y = x + 3 is 1 and the slope of y = -x - 5 is -1 so they are not parallel.

For perpendicular lines m1*m2 = -1 (where m1 and m2 are the slopes).

So these 2 lines are perpendicular.

Angles in a triangle add up to 180
126.7+ 19= 145.7
180-145.7= 34.3 <--- answer
