The fastest way I can come up with is this, and hopefully is the right process. To prove :- s=3r+2 (1) equation of the form ab=0 implies a=0 or b=0, cannot proceed (2) equation of the form ac=0 implies a=0 or c=0. Combining, and understanding that there is no way b=c(look closely at the equations) w...

for perpendicular lines, m1 * m2 = -1 for parallel lines, m1=m2, hence the square(yet to come across a problem where this is asked though) Another tip, To find a slope of a line, just express the line as y=mx + c. Slope will be the value of m. Dont forget, there should be no coefficient for the vari...

You could just try converting 8/9 and 1/8 to decimals if you are comfortable.
8/9 = 0.89
1/8 = 0.125
Lesser values can also give > 1, so E
