11) The standard equations of four lines are given.
1: −2+3=6 2: 2+3=0 3: −2+10=0 4: 3+12=0

a. Find the coordinates of two points on each line.

b. Draw these lines in the given coordinate plane.

c. Which line passes through the origin.

d. Which line is parallel to the x-axis?

e. Which line is parallel to the y-axis?

12) The points A(4,-2),B(-1,1) and C(2,5) are the vertices of a triangle. Plot these points in the
coordinate system and draw triangle ABC. Find
