Answer:

<h2>-6</h2>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (2, -3) and (-1, 15).

Substitute:

m=\dfrac{15-(-3)}{-1-2}=\dfrac{15+3}{-3}=\dfrac{18}{-3}=-6

Can someone explain part c to me please?
Eduardwww [97]

Answer:

)  = 23 °C

ii) = 4.4° C

Step-by-step explanation:

i) The temperature on the surface of the planet.

At the surface of the planet the height is Zero

Therefore, X = 0

Thus; using the equation, the temperature, y will be;

y = 23 - 5x

y = 23 - 5(0)

  = 23 °C

ii) the temperature change for every kilometer from the surface,

From the equation;

y = 23 - 5x

we take, y to be 1

Therefore;

1 = 23 -5x , subtracting 23 on both sides we get

-22 = -5x

x = -22/-5

 = 4.4° C
