Step 1: Set x=0 in the equation of the locus to find the points where it meets the y-axis. The equation of the locus found in the previous question is 3x^2 + 3y^2 + 12x - 38y + 55 = 0. Substitute x=0: 3(0)^2 + 3y^2 + 12(0) - 38y + 55 = 0 3y^2 - 38y + 55 = 0 Step 2: Solve the quadratic equation for y using the quadratic formula y = -b ± sqrt(b^2 - 4ac)2a. Here, a=3, b=-38, and c=55. y = -(-38) ± sqrt((-38)^2 - 4(3)(55))2(3) y = 38 ± sqrt(1444 - 660)6 y = 38 ± sqrt(784)6 Step 3: Calculate the square root and find the two values for y. sqrt(784) = 28 y_1 = (38 + 28)/(6) = (66)/(6) = 11 y_2 = (38 - 28)/(6) = (10)/(6) = (5)/(3) Step 4: State the points where the locus meets the y-axis. Since x=0, the points are (0, y_1) and (0, y_2). The points are (0, 11) and (0, (5)/(3)). That's 3 down. 2 left today — send the next one.
