The first step is since you know what the slope is, you can just plug that into the equation. We now have y=3x+b, b being the y intercept.
3 is equal to 3/1, and you can use that to find the Y intercept. Start at the point that they game you and go up 3 and over 1. But this makes you further away from the Y axis, so you want to do the opposite. Go down 3 and over 1.\
This makes you end up on the Y intercept at (0,1)
Making the equation y=3x+1

Multiply the number by itself zero times , it's the only number which can be multiplied by any other number without changing that other number.
Answer:
The correct answer is 3 x + 2 y = 10.
Step-by-step explanation:
Let us find the midpoint of the given two points (0,2) and (2,5).
The midpoint is given by
.
Let us find the equation of the line passing through the two given points (0,2) and (2,5). We use the formula
where m is the slope of the line and (
) is any point on the line.
Thus the required line is given by 
The line perpendicular to this line would give us the line of reflection.
So the equation of the line of reflection is
( A line perpendicular to
is given by
)
The midpoint (
) should pass through the line of reflection.
Thus this gives the value of k = 10.
So the required line of reflection is given by
