The slope intercept form is y=mx+b, and b represents the y-intercept. In the given equation C=45t+100, 100 is the y-intercept. It represents the one-time fee to join the gym membership.
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
