Write in standard form an equation for the line with slope 1/3 through
the point (2,-2).

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3     Multiply through by 3:

3y + 6 = x - 2

x - 3y  =  6 + 2

x - 3y = 8  < Standard Form.

Step-by-step explanation:

Here we need to estimated quotient of -23.514 and -3.98.

We need to use the division to find the answer.

Before going to the division, we need to estimate the dividend -23.514 and the divisor -3.98 to nearest integer.

-23.514, here the tenths place digit is 5, since it is greater than or equal to 5, we can 1 in the unit place and round off.

So, -23.514 = -24

-3.98, here the tenths place digit is 9 which is greater than or equal to 5, so we add 1 in the unit place and estimate.

So, -3.98 = -4

Now we have to divide -24 by -4.

Remember, when divide a negative by a negative number, the answer will be in positive. This is a division sign rule.
