### Transcript

• 1. Desmos Graphing Calculator Coordinate Geometry Examples Colleen Young
• 2. Desmos Graphing Calculator Use the examples here to help you answer questions on lines and circles
• 3. Desmos Graphing Calculator Note that many slides have hyperlinks which will take you direct to a Desmos page you can experiment with. The images link to a Desmos page.
• 4. Find the equation of a line parallel to 5y+4x=3 which passes through the point (2,-1)
• 5. Describe fully the curve whose Equation is x2+y2=4
• 6. A=(-1,-3) B=(5.7) Calculate the equation of the perpendicular bisector of AB
• 7. Show that the line y=3x-10 is a tangent to the circle x2+y2=10
• 8. Find the equation of the line shown. (through point shown and perpendicular to SR)
• 9. A circle has diameter AB where A=(1.3) and B=(7,-1). Find the equation of the circle. The line y+5x=8 cuts the circle at A and again at D. Find the coordinates of D.
• 10. Find the equation of the line through A (3,1) which is perpendicular to AB
