Answer:
hope this helps
Step-by-step explanation:
I think the answer is b. cos(pi theta)= -0.6
Answer: Negative 1 The slope of parallel lines is the same.
The attachment shows two such lines, given coordinates labeled.
Step-by-step explanation:
Find the slope of the line passing through the given points.
rise/run
Rise is the difference in y-values 7-(-5) = 12
Run is the difference between x-values -5 - 7 = - 12
The Slope is 12/-12 simplify:
slope = -1
300 + 0+ 1, 200 + 50+ 6, 800 +70 + 8.
