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:
<u>STEP ONE: Determine the form of the equation</u>
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:
<u />
<u>STEP TWO: Determine the y-intercept</u>
y = (1 / 2)x + 9
m = 1 / 2
b = 9
Therefore, the y-intercept is <u>9</u>
Hope this helps!! :)
