Calculate the error

#1
Hello everyone,

y = mx + c
I have the following data:
m1= -0.08605 ± 0.07177, c1 = 2.465 ± 1.053,
m2 = -0.01506 ± 0.08479, c2 = 2.141± 1.237
I need to integrate "mx + c" from x = 0 to x = 10 for each set of data and add the final results = integral of (y1) + integral (y2),
How will the error propagate? What is the value of the error in the final anwser.

Thank you.
