Answer:
[see answer below]
Step-by-step explanation:
Slope intercept form is:
![y = mx + b\\\\m - \text{slope}\\\b - \text{y-intercept}](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b%5C%5C%5C%5Cm%20-%20%5Ctext%7Bslope%7D%5C%5C%5Cb%20-%20%5Ctext%7By-intercept%7D)
We are given the slope (m) of 1/2 and the y-intercept (b) of -4.
![y=mx+b\rightarrow \boxed{y=\frac{1}{2}x-4}](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5Crightarrow%20%5Cboxed%7By%3D%5Cfrac%7B1%7D%7B2%7Dx-4%7D)
Hope this helps.
