Q. Which of the following equations represents a line that passes through the points (4,5) (-4,5) and (6,0) (6,0) ?\newlineI. 3x+6y=12 3 x+6 y=12 \newlineII. y=12x+4 y=-\frac{1}{2} x+4 \newlineNeither\newlineI only\newlineII only\newlineI and II
  1. Find Slope: Find the slope of the line using the given points (4,5)(-4,5) and (6,0)(6,0). Slope, m=y2y1x2x1=056(4)=510=12m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 5}{6 - (-4)} = \frac{-5}{10} = -\frac{1}{2}.
  2. Find Y-Intercept: Use one of the points to find the y-intercept bb of the line. Let's use the point (6,0)(6,0). We have m=12m = -\frac{1}{2} and the point (6,0)(6,0). Substitute x=6x = 6, y=0y = 0, and m=12m = -\frac{1}{2} in y=mx+by = mx + b. 0=(12)(6)+b0 = (-\frac{1}{2})(6) + b 0=3+b0 = -3 + b (6,0)(6,0)00
  3. Write Equation: Write the equation of the line in slope-intercept form using the slope m=12m = -\frac{1}{2} and y-intercept b=3b = 3.y=mx+by = mx + by=(12)x+3y = \left(-\frac{1}{2}\right)x + 3
  4. Check Equation I: Check if equation I 3x+6y=123x + 6y = 12 represents the line that passes through the points (4,5) (-4,5) and (6,0) (6,0) . To do this, we can convert the equation to slope-intercept form by solving for y. 3x+6y=123x + 6y = 12 \(\newline6y = -3x + 12\) \(\newliney = (-3x + 12) / 6\) \(\newliney = (-1/2)x + 2\) This equation has the same slope as the one we found, but a different y-intercept. Therefore, equation I does not represent the line that passes through the given points.
  5. Check Equation II: Check if equation II y=12x+4y = -\frac{1}{2}x + 4 represents the line that passes through the points (4,5(-4,5) and (6,0)(6,0). The slope of equation II is 12-\frac{1}{2}, which matches the slope we found. However, the y-intercept is 44, which does not match the y-intercept we found (3)(3). Therefore, equation II also does not represent the line that passes through the given points.
  6. Final Answer: Since neither equation II nor equation IIII has both the correct slope and yy-intercept that match the line passing through the points (4,5)(-4,5) and (6,0)(6,0), the correct answer is "Neither."
