Question
Find the equation of the line passing through the points
P(2, 3) and Q(4, 7).Solution
To find the equation of the line, we first calculate the slope m using the formula: m = (y2 - y1) / (x2 - x1) Substituting the coordinates of points P and Q: x1 = 2, y1 = 3, x2 = 4, y2 = 7: m = (7 - 3) / (4 - 2) = 4 / 2 = 2 Now, using the point-slope form of the equation: y - y1 = m(x - x1) Substituting m, x1, and y1: y - 3 = 2(x - 2) y - 3 = 2x - 4 y = 2x - 1 Thus, the equation of the line is: Correct Answer: b) y = 2x - 1.
