What is the slope of the line which passes through (–6, 0) and (4, 0)?
|dw:1319609801076:dw|
\[\Delta Y \div \Delta X\] Or "change in Y over change in X" or "rise over run" So: \[(0 - 0) \div (4--6)\]\[=0 \div 10\]\[=0\]
However, the answer is zero, right?
Yes, the slope is 0. Meaning the line will run parallel to the x-axis, offset by whatever constant is added. Generally the equation used is:\[y = mx + c\] or something equivalent. So the line would run parallel to the x-axis at the y value of whatever 'c' is equal to.
