To determine the coefficient k in the equation of the function y = kx – 2, it is necessary to substitute the coordinates of the point C (3; 1), which belongs to the graph, into the equation.
1 = k * 3 – 2.
To solve the equation you need:
split variables – move the variable to the left, and collect free terms on the right: 3 k = 1 + 2;
give similar ones: 3 k = 3;
divide right and left sides by 3: k = 1.
Answer: coefficient k = 1, and the equation has the form y = x – 2
