Step-by-step explanation:
Hey there!
The given points are; (8,2) and (8,4).
Note: Use slope formula.
Now;

Keep all values.

Simplify it.

When we divide any number by "2" the result is undefined.
Therefore, the slope of the points is undefined.

The answer is -3 . Use the gradient formula y2-y1/x2-x1
1000/7 = <span>142.857142857
Because this is not an even number we take "142", then times it by 7 teachers.
142*7= 994
1000 - 994 = 6 Pencils left</span>
Answer:
They are not parallel because their slopes are not equal
Step-by-step explanation:
Answer: 30 goldfish
Step-by-step explanation: Bruce has 18 goldfish. If Isabelle has 5 times as many goldfish as Bruce she will have 18*5=90 goldfish. If Arlene has 1/3 times as many goldfish as Isabelle she will have 90/3=30 goldfish.
