Q. A line in the xyxy-plane passes through the point (4,1)(4,-1) and is perpendicular to the line with equation y=x+5y=x+5. Which of the following is an equation of the line?\newlineA. y=x+3y=x+3\newlineB. y=x3y=x-3\newlineC. y=x+3y=-x+3\newlineD. y=x3y=-x-3
  1. Identify slope: Identify the slope of the given line y=x+5y = x + 5.
  2. Determine perpendicular slope: Determine the slope of the line that is perpendicular to the given line.
  3. Use point-slope form: Use the point-slope form to find the equation of the line passing through the point (4,1)(4, -1) with a slope of 1-1.
  4. Simplify equation: Simplify the equation to get it into slope-intercept form, y=mx+by = mx + b.
