Question 8

y= 2,9
What is the y-intercept of the linear equation? (Only input the y-coordinate)

Answer 1

The y-intercept is -9.

Explanation:

Using the form y = mx + b, b is the y-intercept of the equation. Thus by definition in the equation y = 1/2x - 9, -9 is the y-intercept.

Additionally, the y-intercept is the point where x = 0; thus, when y = 1/2(0) - 9, y = -9.
