Your equation would be y = -3x + 2.
A property of parallel lines is that they all have the same slope, which means that as the slope of y = 5 - 3x is -3 (because it is attached to the x), the slope of the parallel lines must also be -3.
You can finish the equation by seeing that the point they have given you is on the y axis, as x is 0, and so it is the y intercept for this line. This means that your final equation is y = -3x + 2.
I hope this helps

Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
Answer:
its 124 degrees as well
Step-by-step explanation:
this is because when two lines are parallel and a single line passes through them the same part at both of the parallel lines have the same angle value
