Answer: Fourth Choice. 9

Concept:

Here, we need to know the idea of linear equations.

Linear equations are equations of the first order or basically in a straight line.

Linear equations can appear in different forms.

  • Slope-intercept form: y = mx + b
  • Point-slope form: y - y₁ = m (x - x₁)
  • Standard form: Ax + Bx = C
  • Intercept form: x / x₁ + y / y₁ = 1

Solve:

STEP ONE: Determine the form of the equation

y = (1 / 2)x + 9

There is a [m] and a [b], therefore, it is slope-intercept form.

In slope-intercept form, y = mx + b, where:

  • m = slope
  • b = y-intercept

STEP TWO: Determine the y-intercept

y = (1 / 2)x + 9

m = 1 / 2

b = 9

Therefore, the y-intercept is 9

Hope this helps!! :)
