Answer:
1st option
Step-by-step explanation:
Given
5y - 7x = 7 ( add 7x to both sides )
5y = 7x + 7 ( divide the terms by 5 )
y = x +
Answer:
B
Step-by-step explanation:
First, find the slope by using change in y divided by change in x.
Change in y = 5 - 2 = 3
Change in x = 2 - 1 = 1
This means that the slope is 3/1 = 3.
Then, you put it in the point-slope form so:
(y - 2) = 3(x - 1)
Answer:8
Step-by-step explanation: behind the x value (5) there are 2 ages that had a value. You add the two values (5+3) and you get 8.
Final answer is 8.
