What is the slope of a line between the points (1, 4) and (-1, 5)? *

Slope m = 1/-2

Step-by-step explanation:

Given the formula for slope of a line to be

m = y - y_1 / x - x_1

Only if a point is given

But in this case, we are given two points

( 1 ,4 ) and ( -1 , 5)

x_1 = 1

y_1 = 4

x_2 = -1

y_2 = 5

Inserting the values given into the formula

m = y_2 - y_1 / x_2 - x_1

m = 5 - 4 / -1 - 1

= 5 - 4= 1

= -1 - 1 = -2

m = 1/ -2

Therefore, the slope of the line is 1 /-2
