Answer:


First we calculate the slope (which is called "m".


Slope = m = (Y2 -Y1) ÷ (X2 -X1)


m = (-8 -1) / (5 -2) = -9 / 3 = -3


We next fill in this equation: b = y -mx


We know m = -3 and we can choose a point (2, 1) to calculate "b"


b = 1 --3 * 2 b = 7


Putting this into y = mx +b


y = -3x +7

The required scale model will be 1:6.24  10^9

<h3>Finding scale factors</h3>

A  scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.

Given the following parameters

Distance of sun to Jupiter = 7.8 * 10^8 km

If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;

n = 8 * 7.8 *10^8

n = 62.4 * 1068

n = 6.24  10^9

Hence the required scale model will be 1:6.24  10^9

Let's solve for g. w = k g

Step 1: Multiply both sides by g.

gw = k

Step 2: Divide both sides by w.

gw/w = k/w g = k/w

Answer g = k/w
