Answer:

The equation of a line parallel to 3x - y= -2 and passes through the point (0, -3) is -3x + y + 3 = 0

Explanation:

Here , the given equation of line 1 : 3x - y= -2

The Slope form of the equation is y = m x + c

⇒3x + 2 = y , where m = 3 is the slope for the line 1

Now, as the Line 2 is parallel to Line 1,

Slope of Line 1 (m1) = Slope of Line 1 (m2)

Hence, the slope of line 2 = 3

Now, by POINT SLOPE FORMULA

The equation of line with point (x0, y0) is given as

(y - y0) = m (x - x0)

For the point (0,-3) the equation of Line 2 is:

y - (-3) = 3 ( x-0)

or, y + 3 = 3x ⇒ -3x + y + 3 = 0

Hence, the equation of a line parallel to 3x - y= -2 and passes through the point (0, -3) is -3x + y + 3 = 0
