Final answer:
To find the standard form equation of a line passing through two points, calculate the slope using the coordinates, use the point-slope form, and then convert it to standard form.
Step-by-step explanation:
The correct answer is option standard form equation of the line. To find the equation of the line that passes through points P(6, 2) and Q(8, -4), we first calculate the slope (m) of the line using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are coordinates of the points P and Q, respectively. After finding the slope, we use the point-slope form of the line equation: y - y1 = m(x - x1) and substitute either point into this equation to solve for y. This will give us the slope-intercept form of the equation, which can then be converted to standard form (Ax + By = C), where A, B, and C are integers, and A should be non-negative.
In this particular case, the slope m becomes ((-4) - 2) / (8 - 6), which simplifies to -6 / 2 = -3. The slope-intercept form using point P(6, 2) would be y - 2 = -3(x - 6). Simplifying, y = -3x + 20. Converting to standard form gives us 3x + y = 20, which is the final answer.
