If these two lines are parallel, they would have the same gradient.
Since Gradient = Rise / Run,
8 / -12 : -4 / 1
These two ratios are obviously not the same, so we can conclude the lines are not parallel.
Answer:
10
Step-by-step explanation:
Slope (m) of two points is expressed as :
m = (y2 - y1) / (x2 - x1)
Given m = 2
the equation becomes;
2 = (r - 2) / (10 - 6)
2 = (r - 2) / 4
cross multiplying becomes ;
2 * 4 = r - 2
8 = r - 2
r = 10

Step-by-step explanation:
Hypotenuse of a right angle triangle from pythagoras theorem is given by
h²=b²+a²
Making h the subject
h=√(b²+a²)
Where h is hypotenuse, b is base and a is the other side of a triangle
10²+24²=676
√676=26 units
72²+21²=5625
√5625=75 units
12²+35²=1369
√1369=37 units
18²+80²=6724
√6724=82 units
105²+100²=21025
√21025=145 units
16²+30²=1156
√1156=34 units
Check the picture below, let's use those two points on the line to get its slope.
