Determine how many lines can have a given slope, and how many lines can have a given slope while passing through a given point. Q8. Find the values of p for which the pair 4x + py + 8 = 0 and 2x + 2y + 2 = 0 has a unique solution. Q9. Find a and b so that (a + b)x − 2by = 5a + 2b + 1 and 3x − y = 14 have infinitely many solutions. Q10. Find k so that x + 2y = 3 and (k − 1)x + (k + 1)y = k + 3 coincident lines. Q12. : Jacob checks his digital watch at a certain time. The first reading is a minutes af two o'clock. Fifteen minutes later, the reading is b minutes after three o'clock. If a is six times b, determine the time of the second reading. Q13. ⭐ Challenge question: The digits of a two-digit number add up to 15. Reversing the digits produces a number 9 greater than the original. Find the number. Q14. ⭐ Challenge question: In cyclic quadrilateral ABCD, the angles are A = (x + 7)°, B = (y + 8)°, C = (3y + 23)° and D = (4x + 12)°. Find all four angles.
