General line equations

In all examples, write the GENERAL EQUATION OF a line that is given in some way.

A) the line is given parametrically: x = - 4 + 2p, y = 2 - 3p

B) the line is given by the slope form: y = 3x - 1

C) the line is given by two points: A [3; -3], B [-5; 2]

D) the line intersects the y-axis at point 0; 6 and has a slope k = 2


p1 = (Correct answer is: ) OK
p2 = (Correct answer is: ) OK
p3 = (Correct answer is: ) OK
p4 = (Correct answer is: ) OK

Step-by-step explanation:

x=4+2p y=23p  3x=12+6p 2y=46p  p1:3x+2y+8=0=0:1
y=3x1  p2:3xy1=0=0:1
ax+by+c=0 c=19  a 3+b (5)+c=0 a (5)+b 2+c=0 a 3+b (5)+19=0 a (5)+b 2+19=0  3a5b=19 5a2b=19  a=7 b=8  p3:7x+8y+19=0=0:1
y=kx+q k=2  6=k 0+q 6=2 0+q  q=6  p4:y=2 x+6  p4:2xy+6=0=0:1
