Answer: m=-11
Step-by-step explanation:
To find the slope of the line, you want to use formula 
. Since we are given two points, we can directly plug them in and solve.
Now, we know that the slope is -11.
Which question are you talking about 1 or 2?
Answer:
range = maximum value - minimum value
Step-by-step explanation:
so here..the maximum value is 20 and the minimum value is 7
20-7 is 13=range
Answer:
first one i think Good luck
Answer:
Line m is not parallel to Line n.
Line m is perpendicular to Line k
Step-by-step explanation:
1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel
2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
