What is the distance between (1, 2) and (4, 2)?

Explanation:
You're measuring how far apart two points are on the plane. Use the distance formula: distance = sqrt((Δx)^2 + (Δy)^2). Here Δx = 4 − 1 = 3 and Δy = 2 − 2 = 0. So distance = sqrt(3^2 + 0^2) = sqrt(9) = 3. Since the y-values are the same, this is just the horizontal distance along the x-axis, which is 3 units.
