Someone please help me

Slope = 4

Step-by-step explanation:

Hi!

So, I can only see question a, so I will answer that.

This is asking for the slope given 2 points.

The line-slope formula states :

where m is the slope and the x and y values are the corresponding values from 2 coordinate points. The hard part of this is deciding which of your points is point 1 and which is point 2. It's arbitrary, so any selection is correct. We just have to stay consistent.

Let's let (3,12) be point 1 and (4,16) be point 2. Now we can write the corresponding x and y values into our formula:

So, the slope of the line through the 2 points (3, 12) and (3, 16) is 4

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
