Q. Which of the following equations represents a line that passes through the points (0,5) (0,5) and (6,3) (6,-3) ?\newlineI. 4x+3y=12 4 x+3 y=12 \newlineII. y=43x+7 y=-\frac{4}{3} x+7 \newlineNeither\newlineI only\newlineII only\newlineI and II
  1. Calculate Slope: Find the slope of the line passing through the points (0,5)(0,5) and (6,3)(6,-3). The slope mm is calculated using the formula m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}. Here, (x1,y1)=(0,5)(x_1, y_1) = (0, 5) and (x2,y2)=(6,3)(x_2, y_2) = (6, -3). m=3560=86=43m = \frac{-3 - 5}{6 - 0} = \frac{-8}{6} = \frac{-4}{3}.
  2. Write Point-Slope Equation: Use the slope and one of the points to write the equation of the line in point-slope form.\newlineWe can use the point (0,5)(0,5) and the slope 43-\frac{4}{3}.\newlineThe point-slope form is yy1=m(xx1)y - y_1 = m(x - x_1).\newlineSubstituting the values, we get y5=(43)(x0)y - 5 = (-\frac{4}{3})(x - 0).
  3. Convert to Slope-Intercept Form: Convert the point-slope form to slope-intercept form y=mx+by = mx + b.\newliney5=(43)x+0y - 5 = \left(-\frac{4}{3}\right)x + 0\newlineAdd 55 to both sides to solve for yy.\newliney=(43)x+5y = \left(-\frac{4}{3}\right)x + 5.
  4. Check Equation I: Check if equation I 4x+3y=124x + 3y = 12 is the same line.\newlineTo check, we need to convert this equation to slope-intercept form.\newline3y=4x+123y = -4x + 12\newliney=(43)x+4y = \left(-\frac{4}{3}\right)x + 4.\newlineThis is not the same as y=(43)x+5y = \left(-\frac{4}{3}\right)x + 5, so equation I does not represent the line passing through the points (0,5)(0,5) and (6,3)(6,-3).
  5. Check Equation II: Check if equation II y=(43)x+7y = -\left(\frac{4}{3}\right)x + 7 is the same line.\newlineCompare this equation with the one we derived y=(43)x+5y = \left(-\frac{4}{3}\right)x + 5.\newlineThe slopes are the same, but the y-intercepts are different 77 vs. 55.\newlineTherefore, equation II also does not represent the line passing through the points (0,5)(0,5) and (6,3)(6,-3).
