Question

Which of the following equations represents a linear function?

2x - 4 = 6
x = -2
y = 1/2 x^{2}
y = 2/3x + 4

Answer 1

The equation that represents a linear function is:

y = 2/3x + 4

This equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. The presence of a single variable x raised to the power of 1 (no exponent other than 1) indicates a linear relationship between x and y.
