  3. y = x + 1
  4. y = -x + 2

Questions & Step-by-Step Solutions

What is the equation of the line that passes through the point (2, 3) and has a slope of -1?
  • Step 1: Identify the point and slope. The point is (2, 3) and the slope is -1.
  • Step 2: Use the point-slope form of the equation of a line, which is y - y1 = m(x - x1). Here, (x1, y1) is the point (2, 3) and m is the slope -1.
  • Step 3: Substitute the values into the point-slope form: y - 3 = -1(x - 2).
  • Step 4: Simplify the equation. Distribute -1: y - 3 = -x + 2.
  • Step 5: Add 3 to both sides to solve for y: y = -x + 2 + 3.
  • Step 6: Combine like terms: y = -x + 5.
