Answer:
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
slope of a line
Different words, same formula
Teachers use different words for the y-coordinates and the the x-coordinates.
Some call the y-coordinates the rise and the x-coordinates the run.
Others prefer to use Δ notation and call the y-coordinates Δy , and the x-coordinates the Δx .
slope of a line
These words all mean the same thing, which is that the y values are on the top of the formula (numerator) and the x values are on the bottom of the formula (denominator)!
slope of a line
Example One
The slope of a line going through the point (1, 2) and the point (4, 3) is 13.
Remember: difference in the y values goes in the numerator of formula, and the difference in the x values goes in denominator of the formula.
