Answer:

#sqrt66.41# or #~~8.15#

Explanation:

The distance between two points is shown by the formula:
#d = sqrt((x_2-x_1)^2 + (y_2-y_1)^2)#

We have the values for the two coordinates, so we can substitute them into the distance formula:
#d = sqrt((4.9 - 2.9)^2 + (-3.0 - 4.9)^2)#

And now we simplify:
#d = sqrt((2)^2 + (-7.9)^2)#

#d = sqrt(4 + 62.41)#

#d = sqrt(66.41)#

If you want the exact distance, you can leave it as #sqrt66.41#, but if you want it in decimal form, it is #~~8.15# (rounded to nearest hundredth's place).

Hope this helps!
