Answer:
1. A. slope = 5/2
2. A. slope = 1
Explanation:
To find the slope you can input the x and y values of two points into this expression:

1. To find the slope, I'm going to use points (2, 3) and (4, 8). Let's input them into the expression:

Simplify:
8 - 3 = 5
4 - 2 = 2
The slope is 5/2.
2. To find the slope, I'm going to use points (0, 0) and (1, 1). Let's input them into the expression:

Simplify:
1 - 0 = 1
1 - 0 = 1
The slope is 1/1, or just 1.
