To find the slope of the line passing through the points \((\frac{1}{2}, -\frac{4}{3})\) and \((\frac{7}{15}, \frac{4}{3})\), we use the slope formula:
Here, \((x_1, y_1) = (\frac{1}{2}, -\frac{4}{3})\) and \((x_2, y_2) = (\frac{7}{15}, \frac{4}{3})\).Substitute these values into the formula:
Simplify the numerator:
Now, simplify the denominator:
To subtract these fractions, find a common denominator. The least common multiple of 15 and 2 is 30.Convert
to a fraction with a denominator of 30:
Convert
to a fraction with a denominator of 30:
Now subtract the fractions:
So the slope
is:
Therefore, the slope of the line passing through the given points is
