Answer:
Y=3x+2
Step-by-step explanation:
first you have to put it in the formula y = mx + c
Y=3-x
in this format c = 0 so there's no intercept
Y=3x+c
The parallel line will have the same gradient but different intercept.
Now we substitute the coordinates(1,5) into the formula.
y = 5
x = 1
5=(3*1)+c
5=3+c
Now we make c the subject.
c=2
So the answer is:Y=3x+2
