SUMMARY

The discussion focuses on finding intersection points between lines and conic sections, specifically ellipses and hyperbolas, using algebraic methods. The first problem involves a line through (3,1) with a slope of -1/2 intersecting an ellipse defined by points (-3,0) and (-2,2), where parameters b=10/4 and a^2=9 are identified. The second problem features a line through (-1,-1) with a slope of 2 intersecting a hyperbola defined by points (2,0) and (-3,-1), with parameters b=1 and a^2=4 established. The discussion highlights the need for additional information regarding the specific equations of the conics to proceed with the solutions.

PREREQUISITES
  • Understanding of conic sections, specifically ellipses and hyperbolas.
  • Knowledge of algebraic methods for solving systems of equations.
  • Familiarity with slope-intercept form of linear equations.

Homework Statement


Find the intersection points of: Line through (3,1) with slope -1/2, and ellipse through (-3,0) and (-2,2). No graphing just algebra.


The Attempt at a Solution


So far I have b=10/4 and a^2=9. I'm not sure how to finish this problem.

Homework Statement


Find the intersection point of: Line through (-1,-1) with slope 2, and hyperbola through (2,0) and (-3,-1). No graphs just algebra.



The Attempt at a Solution


So far I have b=1 and a^2=4. Again, not sure where to go from here. Any pointers?

There are zillions of ellipses passing through (-3,0) and (-2,2). What haven't you told us? Same with the hyperbola.
