Answer:
5 : 16
Step-by-step explanation:
Tucker has a total of 5 + 6 + 5 = 16 coins. The ratio of 5 pennies to that total is ...
pennies : total coins = 5 : 16
Parallel lines have the same slope, in this case 3.
To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.
1=3(2) + b
Solve this and you get -5 as the y intercept.
The equation is y=3x-5
