Answer:
y = 1/2x-5
Explanation:
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and b is the y-intercept
All you really have to do here is replace m with 1/2, which is the slope you gave, and replace b with -5, the y-intercept you gave, in the equation y=mx+b. And you will get y = 1/2x-5
