How do you find the area of this triangle.

The slope of a line is –2 and its y-intercept is (0, 3). what is the equation of the line that is parallel to the first line and passes through (2, 2)? a. 2x + y = 6 b. y = –2x + 3 c.y=1/2x +6 d.y=-2x-6

Can someone check if i did this correct. it’s number 4 if you’re wondering.
