Q. The graph showrs the proportional relationship. Derive the equation of the line y=mx through the origin.(1 point)
Understand the Problem: Understand the problem.We need to find the equation of a line that passes through the origin and has a proportional relationship between y and x, which means y is directly proportional to x.
Point-Slope Form: Use the point-slope form of a line's equation. The point-slope form is y−y1=m(x−x1), where (x1,y1) is a point on the line and m is the slope. Since the line passes through the origin, (x1,y1) is (0,0).
Substitute Origin: Substitute the origin into the point-slope form.Substituting (0,0) into the equation gives us y−0=m(x−0), which simplifies to y=mx.
Verify Equation: Verify the equation.The equation y=mx represents a line passing through the origin with a slope of m, which is what we were looking for.
