Answer:
y = 1/2x + 1
In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.
-2 ⇒ 1/2
Next, we need to substitute the information given into the point-slope formula.
The point-slope formula is:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 0)
y - 1 = 1/2x
y = 1/2x + 1
Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
Incomplete question. Here's the full question:
At the beginning of the day, the stock market goes up 30 1/2 points. At the end of the day, the stock market goes down 120 1/4 points. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
<u>-15%</u>
Step-by-step explanation:
First, we convert the fraction to a whole number;
At the beginning of the day: = 15 (30*1 / 2)
At the end of the day: = 30 (120 * 1 / 4)
Next, since we are told that at the end of the day, the stock market goes down, it means we will subtract any gain it had by the change;
%
Hence, the total change in the stock market from the beginning of the day to the end of the day is <u>-15%.</u>
