Okay so, I have to write an equation in standard form, of a line that passes through the given point and has the given slope, ( M) or that passes through the given points.

Heres what I think:

1)( 4,-1) M= 3
So, it's in y=3x+B
and then, I would plug in
-1 for y, and 4 for x.

So, -1=3(4)+B
-1=12+B
Subtract 12 from -1
and get 13.
B=13
Full equation:
y=3x+13
But, how would I write this in standard form?

Could a tutor please explain to me?

Thank you.

It is already in the standard form, but the correct answer is
y = 3x - 13

You made an error after the line
-1 = 12 + b

I sure you will see it right away when you check that step.
no, that form is slope intercept form.

Isn't it?
Some people consider that the standard form. If you want it in Ax + By = C form,
or Ax + By + C = 0, it is easily rearranged.

But first correct the error.

3x - y = 13
