Answer:
1,75 m
Step-by-step explanation:
The radius is by definition half of the diameter and so the half of 3.5 m is 1.75 m
Since the line is vertical, its slope is "undefined." This slope has no numerical value.
The point-slope form is y = mx + b. In this particular problem, the slope, m, is undefined, and there is no y-intercept (the line never crosses the y-axis).
