Questions and Answers

Given a slope of 2 and a point (3, 5), what is the equation of the line in point-slope form?

  • $y = 2x + 5$
  • $y = 2x - 1$
  • $y - 5 = 2(x - 3)$ (correct)
  • $y = 2(x + 3) - 5$

    • Given a slope of -3 and a point (-2, 4), what is the equation of the line in slope-intercept form?

  • $y - 4 = -3(x + 2)$
  • $y = -3x - 2$
  • $y = -3x + 10$ (correct)
  • $y = -3(x + 2) + 4$

    • Given a slope of 1/2 and a point (4, -3), what is the equation of the line in standard form?

  • $2x - y = 11$ (correct)
  • $y + 3 = rac{1}{2}(x - 4)$
  • $y = rac{1}{2}x - 5$
  • $y = rac{1}{2}x + 1$
