Equation of a straight line parallel to x + y = 7, whose x-intercept is 3 units, is x + y = 3. Explanation: Any line parallel to x + y = 7 will have the same coefficients for x and y, so the equation looks like x + y = k, Using the intercept: An x-intercept of 3 means the line passes through the point (3, 0), Let’s solve for k: Plug (3, 0) into the equation, 3 + 0 = k ∴ k = 3 Substituting k back gives x + y = 3.
