The slope of a line between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by $\frac{y_2 - y_1}{x_2 - x_1}$ . You can think of this as either rise/run or change in y divided by change in x.

Here, the slope is $\frac{6-4}{2-1}$ , which is equal to 2.

Part 2. Two different rectangular prism

Step-by-step explanation:

Let

x ----> the number of modules

y ---> the number of stories

we have

x=150\ modules\\y=15\ stories

How do you do coordinates?

suter [353]

Answer:

Start at (0, 0), or the origin. Just go to (0, 0), which is the intersection of the x and y axes, right in the center of the coordinate plane. 2. Move over x units to the right or left. Let's say you're working with the set of coordinates (5, -4). Your x coordinate is 5.
