What is the constant of variation k of the direct variation, y = kx through (–3, 2)?
Linear equations are one of the most important concepts of mathematics. They are used to represent straight lines on the cartesian plane. Let's solve a problem related to linear equations.
Answer: The constant of variation k for y = kx through (-3, 2) is k = -2/3.
Let's understand the solution in detail.
In the above question, if the point given passes through (x, y), then we substitute the values of the coordinates in the equation y = kx to find the value of k.
Therefore, (2) = (-3) × k.
Finally, k = -2/3.
