The graph shows the height of a plant after a certain amount of time measured in days.
Do you think that there may be a proportional
relationship between the number of days and the
height of the plant? Explain your reasoning.
The graph shows how much snow fell after a certain amount of time
measured in hours.
2. Do you think that there may be a
proportional relationship between the number of
hours and the amount of snow that fell? Explain
your reasoning.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
