SAT Math· difficulty 3/5

A line passes through (−2,5)(-2, 5) and has slope −12-\frac{1}{2}. Which point also lies on the line?

  • A

    (0,4)(0, 4)

    check_circle
  • B

    (4,1)(4, 1)

  • C

    (0,6)(0, 6)

  • D

    (2,4)(2, 4)

Explanation

Equation: y−5=−12(x+2)y - 5 = -\frac{1}{2}(x + 2), so y=−12x+4y = -\frac{1}{2}x + 4. Check (0,4)(0, 4): y=4y = 4. Yes.
