Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
Ok the diameter would be 0.000000024cm
because 1.2 x 0.00000001 = 0.000000012
that is the radius so we multiply by 2 to get the diameter
0.000000012 x 2 = 0.000000024
