Answer:
The answer is
Step-by-step explanation:
when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:

See the attachment for a plot
Step-by-step explanation:
I find it convenient to plot lines using their x- and y-intercepts, when those are integers. To find the intercepts, we can divide the equation by the constant on the right:
x/10 +y/5 = 1
This is "intercept form". The denominator in each term is the corresponding intercept:
the x-intercept is 10, point (10, 0)
the y-intercept is 5, point (0, 5)
We can choose another value of y to find a third solution. Let y=2. Then we have ...
-x -2(2) = -10 . . . . . put 2 for y in the original equation
-x = -6 . . . . . . . . . . add 4
x = 6 . . . . . . . . . . . . multiply by -1
A third point is (6, 2)
