Did I do these two right?
1. Write an equation of the line that passes through the point (3,0) and has the slope, m = -2.
I put Y = -2X + 6
2. Write an equation of the line that passes through the point (1,2) and has the slope, m = 2.
I put Y = 2X + 0

1) this called "SLOP"
and we solve by this rule
Y-Y1=m(X-X1)
what is the Y and Y1 and X and X1 they are the points
which she gave it to you in the question and the (M) is the slop
(3,0) the Y1 is (0)and the X1 is (3)
the solution going to be like this for the first question
Y-0= -2(X-3)
Y-0= 2x + 6
Y = - 2X + 6 this is the final answer for the first one
2) Y-2= 2(X-1)
Y - 2 = 2x - 2
Y = 2x this is the final answer for the second one
*i remove the -2 because we have -2 in the other side so when i move the left side -2 to the right side it is going to be
-2+2 =0

Yes you did it right.
If you want further confirmation, I did it out for you below:
1.) Point (3,0) m=-2
so, y = -2x + b
we have to find the y-intercept, which is b.
so substitute 3 in the place of x and 0 in the place of y.
0 = -2(3) + b
b = 6
so, Y = -2x + 6
Same goes for the second one.
Both answers are right.

I can't tell you if you did the problems right because you didn't show your work. However, your answers are correct.
