2.(7,5)
3.(-7,-5)
4.(5,7)
Answer:
First find the slope of the straight line, m=(Y2-Y1)/(X2-X1)=(17–7)/(-5–0)=-2.
Using the standard equation of a straight line, y=mx+b, we know that m=-2.
Thus, so far we know that y=-2x+b.
Now plug in the coordinates of either of the above points, that we know do lie on the straight line, into our equation, y=-2x+b, and solve for b.
I will use the first point, (0,7), to get 7=(-2)(0)+b.
Solving for b, we see that b=7.
Therefore, the equation of the straight line is y=-2x+7.
It is a good idea to check your answer on a graphing calculator.

The missing number in the sequence is 54.
The missing number in the sequence is 54.
To identify the missing number, we need to observe the pattern in the sequence. The sequence decreases by 12 each time. Starting from 78, we subtract 12 to get 66, then subtract 12 again to get 54, and so on. Therefore, the missing number is 54.
The number of cupcakes needed to get the order to 100% is 6 cupcakes.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
60% = 9 cupcakes
Multiply 100/60 on both sides.
100/60 x 60% = 100/60 x 9 cupcakes.
100% = 5 x 3 cupcakes
100% = 15 cupcakes
Thus,
6 morecupcakes are needed.

Answer:
6 more cupcakes.
Step-by-step explanation:
60% of 15 is 9, so 15-9 is 6.
