Given the equation y = 2x - 5 and the domain {-1, 4} find the slope

i need with this and if you do can you show the work

The slope  is m=2

Step-by-step explanation:

we have

This is the equation of a line in slope intercept form

where

m is the slope

b is the y-coordinate of the y-intercept

therefore

The slope m is equal to

Alternative Method

we know that

The formula to calculate the slope between two points is equal to

we have

 and the domain {-1, 4}

For x=-1

point (-1,-7)

For x=4

point (4,3)

substitute the values in the formula of the slope

i believe the answer is letter c) 8

step-by-step explanation:
