The slope is the change in Y over the change in X
Slope = (10 - -13) / (14 -12)
Slope = 23/2
Y = -8x - 5/4......slope here is -8 or -8/1
y = 1/8x + 4/5...slope here is 1/8
what u have here are negative reciprocal slopes....negative reciprocal of a number can be found by flipping the number and changing the sign. So the negative reciprocal of -8/1 is 1/8 (see how I flipped the number and changed the sign)...and when u have negative reciprocal slopes, this means that ur lines are perpendicular.
Answer:
2/15
Step-by-step explanation:
1/5 + 2/3
= 3/15 + 10/15
= 13/15
15/15 - 13/15
= 2/15
Answer:
Step-by-step explanation:
Answer:
150
Step-by-step explanation:
The angle as a whole is 180 degrees. 150 and 30 are supplementary angles because they add up to equal 180.
