Answer:
The fact that there is only one number is okay, just continue the way you usually would.
For example find two points:
when x=0: y=-3(0), y=0
when x=2: y=-3(2), y=-6
(0,0) and (2,-6) are two points on the line. Connect them and extend the line.
Step-by-step explanation:
diameter (d) = 7cm
radius (r)= d/2 .... formula
= 7/2 .....put the value
= 3.5cm
the measure of radius is 3.5cm.
The square root of 128/5 is 5.059644
