Substituting the value of y in the line in the equation of the circle, we have x2 + Qx + b)2 = 4, or 25x2 + 24 6x + (16 62-64) = 0. The roots of this equation, by hypothesis, must be equal; hence the discriminant must vanish (Theorem II, p. 3); that is, 576 62-100 (16 b2-64) = 0, whence 6 = . Third step. Substitute these values of 6 in the equation of the first step. We thus obtain the two solutions and PROBLEMS 1. Write the equations of the systems of lines denned by the following conditions. (a) Passing through (--2, 3). (b) Having the slope--f. (c) Distance from the origin is 3. (d) Having the intercept on the F-axis =--3. (e) Passing through (6, --1). (f) Having the intercept on the X-axis = 6. (g) Having the slope. (h) Having the intercept on the F-axis = 5. (i) Distance from the origin = 4. 2. What geometric conditions define the systems of lines represented by the following equations? (a) 2 x-3 y + 4 k = 0. (b) kx-Zy-7 = 0. (c) x + y--k = 0. (d) x + k = 0. (e) x + 2%-3 = 0. (f) 2 kx-3 y + 2 = 0. (g) x cos a + y sin a + 5 = 0. Hint. Reduce tlie given equation to one of the well-known forms of the equation of the first degree. 4. Find the equations of the straight lines with the slope--T5j which cut the circle x2 + y2 = 1 in but one point. Ans. 5x + 12y = 13. 5. Find the equations of the lines passing through the point (1, 2) which cut the circle x2 + y2 = 4 in but one point. Ans. y = 2 and 4 x + 3 y = 10. 6. Find the equation of the straight line passing through (--2, 5) which makes an angle of 45 with the F-axis. Ans. x + y--3 = 0. 7. Find the equation of the straight line which passes through the point (2, --1) and which is ...Hide synopsis
