To find the x-intercept, substitute y = 0. ⇒ x (ax + b) = 0 ⇒ x = 0 or, x = -b/a Using the mid- point formula, we have: ⇒ x = ⇒ x = -b/2a Hence proved. Sample Problems Question 1. Find the axis of symmetry of the parabola y = x2 − 4x + 8. Solution: Given: y = x 2 − 4x + 8
NettetThe line of symmetry can be discovered in various shapes in any given figure. Vertical line is the line in a coordinate plane that represents the direction from up to down or we can say it goes in that direction. The equation of the straight line is y = mx+c [here, m denotes the slope while b denotes the y-intercept]. NettetThe symmetry line or horizontal axis of a shape which divides the shape into two identical halves is known as horizontal line of symmetry. That means the axis here crosses …
