What is the slope of line k?
A
-2
B
-3
C
2
D
5

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

The slope of the line is of -2, hence option A is correct.

A similar problem, in which the objective is also finding the slope, is given at link

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

idk
