What is the y-intercept of the equation y = 10x - 3?

  1. 0

  2. -3

  3. 10

  4. 3

The correct answer is: -3

The y-intercept is the value of y when x=0. In this equation, the y-intercept is -3, as when x=0, y= 10(0)-3 = -3. Options A, C, and D cannot be the y-intercept as they do not represent the value of y when x=0.
