Answer:
a=-2, b=1.
Step-by-step explanation:
1) according to the condition it is required to find the equation of line, which passes through points A(-3;7) and B(4;-7);
2) the equation of this line can be made up using the formula:
3) if to re-write the last equation, then
y=-2x+1;
4) finally, a= -2; b=1.
Answer:
Negative 3.25 greater-than negative 2.5 + r
Step-by-step explanation:
The solution Ellen drew is ...

Answer:
The formula says that the sum of the first n terms of our arithmetic sequence is equal to n divided by 2 times the sum of twice the beginning term, a, and the product of d, the common difference, and n minus 1. The n stands for the number of terms we are adding together.
