Answer:
14x-10y=-96
Step-by-step explanation:
we know that
The equation of the line in standard form is equal to
Ax+By=C
where
A is a positive integer
B and C are integers
so
we have
y=1.4x+9.6
Multiply by 10 both sides
10y=14x+96
isolate the variable x and y (Remember that A must be positive)
14x-10y=-96 -----> standard form
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:

Small numbers:

However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
