Positive proportion function in grade two of junior high school (just learned today) If the function y = (k-1) x 3K + 5 is a positive proportional function, the value of K is obtained Note: (k-1) x (not a multiplication sign) the degree of X is 3K + 5

Positive proportion function in grade two of junior high school (just learned today) If the function y = (k-1) x 3K + 5 is a positive proportional function, the value of K is obtained Note: (k-1) x (not a multiplication sign) the degree of X is 3K + 5

Because the positive proportion function is a linear function
So 3K + 5 = 1
So k = - 4 / 3
