Answer:
ECHA
Explanation:
You want the slopes of four representations of linear functions.
1. Rise/Run
The line rises 1 unit for each 2 to the right. Its slope is ...
m = rise/run = 1/2 . . . letter E
2. Slope formula
The formula for the slope between two (x, y) pairs is ...
m = (y2 -y1)/(x2 -x1)
m = (-8 -(-12))/(1 -(-1)) = 4/2 = 2 . . . letter C
3. Slope formula
m = (-3 -(-6))/(-4 -2) = 3/-6 = -1/2 . . . letter H
4. Rise/Run
The line rises -2 units for each 1 to the right. Its slope is ...
m = -2/1 = -2 . . . letter A
The puzzle #4 solution is ECHA.
