SSC-IMD-SA-QUANT-MOCK-02 – Question 23

Question:

A line passes through the points \((x, 1)\) and \((5, -3)\) and has a slope of -2. Find the value of \(x\).

एक रेखा बिंदु \((x, 1)\) और \((5, -3)\) से होकर गुजरती है और इसकी प्रवणता (Slope) -2 है। \(x\) का मान ज्ञात कीजिए।

Options:

  • 1
  • 3
  • 5
  • 7
  • 1
  • 3
  • 5
  • 7

Correct Answer: b)

Explanation:

Slope formula: \(m = \dfrac{y_2 – y_1}{x_2 – x_1}\).
\(-2 = \dfrac{-3 – 1}{5 – x} = \dfrac{-4}{5 – x} \implies 5 – x = 2 \implies x = 3\).

प्रवणता का सूत्र: \(m = \dfrac{y_2 – y_1}{x_2 – x_1}\)।
\(-2 = \dfrac{-3 – 1}{5 – x} \implies -2(5 – x) = -4 \implies 5 – x = 2 \implies x = 3\)।
