Answer:
Step-by-step explanation: 50r - 6= 82r-70
Add 50r to 82r which equals to 132 r
Now add the the 70 to the left side so -6+70 should equal 76.
Now it should look like this 76=132r
To get the value of r you have to divide 76/132 on both sides of the equation and your answer should be 0.57=r

Answer:
h=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
-7=(-10-h)/(7-6)
-7=(-10-h)/1
-7*1=-10-h
-7=-10-h
h=-10-(-7)
h=-10+7
h=-3
