Q. The graph showrs the proportional relationship. Derive the equation of the line \newliney=mxy=mx through the origin.\newline(11 point)
  1. Understand the Problem: Understand the problem.\newlineWe need to find the equation of a line that passes through the origin and has a proportional relationship between yy and xx, which means yy is directly proportional to xx.
  2. Point-Slope Form: Use the point-slope form of a line's equation. The point-slope form is yy1=m(xx1)y - y_1 = m(x - x_1), where (x1,y1)(x_1, y_1) is a point on the line and mm is the slope. Since the line passes through the origin, (x1,y1)(x_1, y_1) is (0,0)(0, 0).
  3. Substitute Origin: Substitute the origin into the point-slope form.\newlineSubstituting (0,0)(0, 0) into the equation gives us y0=m(x0)y - 0 = m(x - 0), which simplifies to y=mxy = mx.
  4. Verify Equation: Verify the equation.\newlineThe equation y=mxy = mx represents a line passing through the origin with a slope of mm, which is what we were looking for.
