Answer:
y = -1
Step-by-step explanation:
First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.
Answer: 20%.
Step-by-step explanation:
Given, The price of a shirt is marked down from $12.50 to $10.00.
Previous price = $12.50
New price = $10.00

= $2.50
Now, the percent decrease of the shirt = 

Hence, the percent decrease of the shirt = 20%.

- so here, the situation is about the teacher reading a sentence.
- the favorable outcome is the set which has all the words that the students would not know from all the words read by the teacher or simply from the sample space.
- since the teacher reads the first sentence on the first page in every chapter , all the words in that sentence will be sample in this situation.
