Respuesta :
I think it is either a or b. I think both of them are not expressions for slope.
Option B is correct. The incorrect expression for the slope will be x2-x1/y2-y1.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The slope of the lines is calculated by the formula:-
Slope = Rise / Run = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Therefore Option B is correct. The incorrect expression for the slope will be x2-x1/y2-y1.
