There is no shape, could you give a picture or something of the shape?
We can use the formula y2-y1/x2-x1 to find slope given two points. Therefore, we have -1-8/-2-1, getting us -9/-3, or just 3. Hope this helps!

Step-by-step explanation:
Answer:
Order 5 pizza's. There is
1
2
a pizza left so someone gets an extra portion! Or it is split evenly!
Explanation:
No matter how you present this, the underlying principle is that of ratio.
If each pupil gets
1
4
of a pizza the 1 pizza feeds 4 students.
So the ratio of
pizza count
Student count
→
1
4
Need to have sufficient pizza for 18 students. The ratio will be constant so we have:
Let the count of pizzas be
p
pizza count
Student count
=
1
4
=
p
18
So we now have:
p
18
=
1
4
Multiply both sides by
18
giving:
18
×
p
18
=
1
4
×
18
18
18
×
p
=
18
4
But
18
18
=
1
p
=
18
4
=
4
1
2
You can not order
1
2
a pizza so the total pizza count is 5
The answer is 2/90
Multiply 2/10 by 1/9
This is because the first time there are 2 green marbles and ten marbles total but the second time he had already taken out a green marble so there is only 1 green marble left and 9 marbles total.
Hope this helps :)
