    Study Notes

    • The problem is to find the equation of the line that passes through the point (6,4) and is perpendicular to the line with a slope of 5/3.
    • The equation of a line in point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
    • Since the line is perpendicular to the line with a slope of 5/3, the slope of the desired line is the negative reciprocal of 5/3, which is -3/5.
    • Substituting the point (6,4) and the slope -3/5 into the equation, we get y - 4 = -3/5(x - 6).
    • Simplifying the equation, we get y = -3/5x + 38/5.
    • To verify the result, we can use an online calculator that takes the slope and a point as input and plots the line.
    • The calculator confirms that the line y = -3/5x + 38/5 passes through the point (6,4) and is perpendicular to the line with a slope of 5/3.
