Which is the best approximation for the solution of the system of equations? y=-2/5x+1
y=3x-2

a(0.45, 0.88)
b(0.88, 0.65)
c(0.88, 1.1)
d(1.3, 0.88)

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
