y-3=3(x+1)
opening the bracket
y-3=3x+3
y=3x+3+3
equation of the line in the form y=mx+c;
y=3x+6
therefore gradient=3
parallel lines have same gradient therefore gradient of the other line is 3
y--3/x-0=3
y+3=3(x-0)
y+3=3x-0
y=3x-3.
The answer is (6,-4). By the way, this was very hard to read.
300 minutes equals five hours.
Do you mean the #12 and severe to fifths to a decimals if you are then it's 12.57
