find the equation of the straight line which passes through the point (-1,2) and is
A) parallel to the line with equation x=2
B) perpendicular to the line with equation y+3x=0
C)parallel to the line with equation y-0.6x=4
parallel to the line with eqn x=2 and point (-1,2)
gradient of the line m1= 0
change y/ change x= slope (m) for parallel lines m1 = m2
B.perpendicular to the line with equation y+3x=0 and point (-1, 2)
for perpendicular lines m1*m2=-1
y= mx +c
C.parallel to the line with equation y-0.6x=4
m1=6/10 since for parallel line m1=m2
