Whether two particular equations are parallel to each other depends on their slope.
(a) & (b) since these two equations have the same slope of 1.
y = x + 4 is in the form of y= mx + b where m is the slope of 1.
y = x -7is in the form of y= mx + b where m is the slope.of 1.
(c) & (d) since these two equations have the same slope of 4.
y =4x+11is in the form of y= mx + b where m is the slope of 4.
y =4x–4 is in the form of y= mx + b where m is the slope of 4.

Parallel Lines= the same equation
Perp Lines= Opposite Reciprocals
If a line is written in slope-intercept form, y=mx+b, then the # in front of x is the slope.

interior the formula for a line, y=mx+b, m represents the slope. for 2 lines to be parallel, they might ought to have the comparable slope. interior the provided equations, there are basically 2 that have the comparable m (slope) values, (a) and (c) the two have a slope of 6.

lines a and b have the same gradient of 1 so they r parallel;
similarly lines c and d have the same gradient of 4 so they r parallel as well:
PARALLEL LINES HAVE THE SAME GRADIENT!

two equations are parallel if their slopes are equal.
a and b have the same slope so they are aparallel.
c and d have the same slope so they are parallel

a and b because each has a slope of 1.
also c and d because their slopes are equal to 4

a) and b) are parallel. (gradient = 1)
c) and d) are parallel. (gradient = 4)
