A map has a scale of 4 cm : 4 km. If Union and Clayton are 8 km apart, then
they are how far apart on the map?

8cm

Step-by-step explanation:

So since we know the scale of the map (4cm : 4km or we can also write it down as 1cm : 1km) we will just have to find out how much 4km fits into 8km and then multiply the result by 4cm. So we do the following steps.......

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
