Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?
ikadub [295]
Line M with slope 6 is neither, line n with slope -6 is parallel because only lines with same slope are parallel, line p with slope 1/6 is neither. and line q with slope -1/6 is perpendicular because only the reciprocal of a slope is perpendicular, so reciprocal of 6= 1/6 reciprocal of -6=-1/6 reciprocal of 2= 1/2

Is x+3=-5y in standard form?
skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is Ax+By=C with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

x+3=-5y

Subtract 3 from both sides.

x=-5y-3

Add 5y.

x+5y=-3
