Answer:

y = 3x + 10

Explanation:

If two lines are parallel, that means they have the same slope, so the equation of the line would have a slope of 3: y = 3x + b

Next, find the y-intercept. u can do this by substituting in the values of the set of coordinates the line passes through:

y = 3x + b

1 = 3(-3) + b

1 = -9 + b

10 = b

put the value of b into the equation, and ur done!

y = 3x + 10

hope this helps!
