  1. Find Slope of Line c: The equation for line c is given as y=(37)x+4y = -\left(\frac{3}{7}\right)x + 4. To find the equation of a line d that is perpendicular to line c, we first need to determine the slope of line c. The slope of line c is the coefficient of xx, which is (37)-\left(\frac{3}{7}\right). Since line d is perpendicular to line c, its slope will be the negative reciprocal of the slope of line c. The negative reciprocal of (37)-\left(\frac{3}{7}\right) is 73\frac{7}{3}.
  2. Determine Slope of Line d: Now that we have the slope of line d, which is 73\frac{7}{3}, we can use the point-slope form of the equation of a line to find the equation of line d. The point-slope form is yy1=m(xx1)y - y_1 = m(x - x_1), where mm is the slope and (x1,y1)(x_1, y_1) is a point on the line. We know that line d passes through the point (2,4)(2,4), so we can substitute m=73m = \frac{7}{3}, x1=2x_1 = 2, and y1=4y_1 = 4 into the point-slope form.
  3. Use Point-Slope Form: Substituting the values into the point-slope form, we get y4=(73)(x2)y - 4 = \left(\frac{7}{3}\right)(x - 2). Now we need to simplify this equation to get it into slope-intercept form, which is y=mx+by = mx + b.
  4. Simplify Equation: First, distribute the slope 73\frac{7}{3} across the (x2)(x - 2) term: y4=(73)x(73)2y - 4 = \left(\frac{7}{3}\right)x - \left(\frac{7}{3}\right)*2. Simplifying further, we get y4=(73)x143y - 4 = \left(\frac{7}{3}\right)x - \frac{14}{3}.
  5. Add Constant Terms: Next, we add 44 to both sides of the equation to solve for yy: y=73x143+4y = \frac{7}{3}x - \frac{14}{3} + 4. To combine like terms, we need to express 44 as a fraction with a denominator of 33, which is 123\frac{12}{3}. So the equation becomes y=73x143+123y = \frac{7}{3}x - \frac{14}{3} + \frac{12}{3}.
  6. Final Equation: Combining the constant terms, we get y=73x23y = \frac{7}{3}x - \frac{2}{3}. This is the equation of line dd in slope-intercept form.
