Step-by-step explanation:
If 4 cm represents 8 kilometers then 1 cm represents;
8 / 4
= 2
1 cm : 2 km
How, then, about 5 cm – the distance between Sophie's home and school?
5 cm : ? km
A cross multiplication;
1 cm : 2 km
5 cm : x km

Answer:
<em>y</em> = 45<em>x</em> + 7
Step-by-step explanation:
From the given data, we have ordered pairs (2, 97) and (4, 187). We can use them to find the slope, as such:

We can then use the slope and one of the ordered pairs to find the y-intercept, as such:

Therefore, <em>m</em> = 45 and <em>b</em> = 7. We get the equation:
<em>y</em> = <em>mx</em> + <em>b</em>
<em>y</em> = 45<em>x</em> + 7
