Answer:
y=2/3x-5
Step-by-step explanation:
1. find the slope of the given line
2. find its opposite reciprocal(slope of the perpendicular line)
3. create a new linear equation using the new slope
4. substitute (3,-3) to find b
Answer:
Therefore, option C is true.
Step-by-step explanation:
From the graph, we get the sequence
7, 5, 3, 1, ...
Here,
a₁ = 7 is the first element.
An arithmetic sequence has a constant difference 'd' and is defined by
computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same and equal to
substituting a₁ = 7 and d = -2 in the nth term of the sequence
Therefore, option C is true.
