Answer:

2x +3y = -4

Explanation:

The slope of the line is given by the slope formula:

m = (y2 -y1)/(x2 -x1

m = (-4 -4)/(4 -(-8)) = -8/12 = -2/3

This can be used in the point-slope formula to find an equation of the line:

y -y1 = m(x -x1)

y -4 = -2/3(x -(-8)) . . . . substituting for (x1, y1) and m

Multiplying by 3 eliminated fractions:

3(y -4) = -2(x +8)

3y -12 = -2x -16

Adding 2x+12 to both sides gives the standard form equation:

2x +3y = -4
