Complete the point-slope equation of the line through ( 1, 10) and (5.2).
forsale [732]

Answer:

y = -2x + 12

Step-by-step explanation:

The point-slope equation for a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept(value of y when x = 0).

(1,10)

This means that when x = 1, y = 10. So

10 = m + b

(5,2)

This means that when x = 5, y = 2. So

2 = 5m + b

From the first equation, b = 10 - m. So

2 = 5m + 10 - m

2 = 4m + 10

4m = -8

m = -2

And

b = 10 - m = 10 - (-2) = 10 + 2 = 12

So

y = -2x + 12

Alex has five rolls of shelf paper that is 800 cm long.She wants to use the to line the 1-meter wide shelves in her pantry. How
jeyben [28]

Answer:

Alex can line eight 1-meter wide with the paper.

Step-by-step explanation:

- Alex has five rolls of shelf paper that is 800cm.

- She wants to use the paper to line the 1-meter wide shelves in her pantry.

- We want to determine how many 1-meter wide she can line with the paper.

- First, we know that

100cm = 1m

- we need to determine how many meters are in 800cm.

100cm = 1m

800cm = xm

100x = 800

x = 800/100

= 8

Therefore, 800cm is equivalent to 8m

Alex can line eight 1-meter wide with the paper.
