3.3.1 Coordinate geometry in the (x, y) plane (A-level only)

What is the equation of a line with gradient mmm through (x1,y1)(x_1,y_1)(x1​,y1​)?

A

y−y1=m(x−x1)y-y_1=m(x-x_1)y−y1​=m(x−x1​)

B

114\frac{11}{4}411​

C
  • x=2+3cos⁡tx=2+3\cos tx=2+3cost
  • y=−1+3sin⁡ty=-1+3\sin ty=−1+3sint
D

The direction corresponds to increasing ttt.
