12. Nitrogen is a gas at certain temperatures under normal conditions. These temperatures (1), in degrees Celsius (°C), are represented by the inequality 1. Which best describes the meaning of the inequality?
A. Nitrogen is a gas only if the temperature is below 100G.
B. Nitrogen is a gas only if the temperature is above 195 c.
C. Nitrogen is a gas only if the temperature is at or below 196°C.
D. Nitrogen is a gas only if the temperature is at or above 190C.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

idk
