Hi Kay, the point-slope form of a line is given by: y - y1 = m(x - x1). Substituting the given point, (6, -8), and the slope, -2, gives: y - (-8) = -2 * (x - 6) This becomes: y + 8 = -2x + 12
The standard form of linear equations is:
Ax + By = C
So if the word problem involves the sum or difference of two unknown quantities and the sum or difference is known, then the equation formed will be in standard form.
M (m) is (=) 1/6 of (1/6 times) earth weight (e)
m=1/6 times e
m=e/6
B is the answer
Since you're familiar with the place value associated with decimal digits, you know that the 1 in this number, being 4 places to the right of the decimal point, has a place value of 1×10⁻⁴. This means the number can be written as
1.27×10⁻⁴
