Answer:y=3x-5Step-by-step explanation:Use the point slope formula:

[tex]y-y_{1} =m(x-x_{1})[/tex]

Slope (m)We know the slope is 3, because parallel lines have the same slopes.

y = 3x-13

This is in y=mx+b form, where m is the slope and b is the y intercept. We know that 3 is the slope because it is being multiplied by x.

Point (x1, y1)Points are written like so: (x, y)

So, for (1, -2), 1 is our x1, and -2 is our y1.

Now we know the m is 3, x1 is 1 and y1 is -2, so we can substitute them in

[tex]y-y_{1} =m(x-x_{1})[/tex]

y- -2=3(x-1)

y+2=3(x-1)

y+2= 3*x + 3*-1

Distribute the 3y+2=3x-3

y+2-2=3x-3-3

Subtract 2 from both sidesy=3x-5Answer:y = 3x – 5

Step-by-step explanation:If a line is parallel to another line, the slopes are the same. This means that the equation we will find is y = 3x + b, where b is real.

Plug in point-2 = 3(1) + b

Simplify-2 = 3 + b

Simplify-5 = b

y = 3x -5
