The slope of a line hat contains the following points: (17, -12) and (7, 8) is -2.
<h3>How to find the slope of a line?</h3>
The slope of a line is the change in dependent variable with respect to the change in the independent variable.
The slope of a line is rise over run.
The slope of a line can be represented as follows;
m = slope = y₂ - y₁ / x₂ - x₁
Hence, using (17, - 12) and (7, 8)
x₁ = 17
x₂ = 7
y₁ = - 12
y₂ = 8
slope = 8 + 12 / 7 - 17
slope = 20 / - 10
slope = -2

Answer:
-11°C or 1°C
Step-by-step explanation:
The question said that, by the noon, the temperature changes by 6°C, but it doesn't tell you if it changes for a hotter or colder temperature, so its possible the temperature at the noon to be:
-5 -6 = -11°C
or
-5 +6 = 1°C
To graph the possible temperatures, you have to draw a dot at the numbers -11 and 1
