Finding the Slope of the Line Between and
To calculate the slope of the line that passes through the points and , we apply the slope formula: . First, we designate one point as , such as , and the other point as , such as . Substituting these coordinates into the formula gives . Since subtracting a negative number is equivalent to adding a positive number, the numerator evaluates to , and the denominator evaluates to . Thus, the slope is . We can visually verify this calculation by plotting the points on a coordinate graph and drawing a right triangle. Moving from the first point to the second, the vertical rise is units upward, while the horizontal run is units (moving units to the left). This gives the same ratio of rise over run, .
