Question 133650: Need to find the slope of a line parallel to the graph of each equation.
y=4x + 2
and
y=2/7x + 1

Help! I teach 5th grade not 7th. Can't even begin to explain it to my son.

parallel lines have the SAME slope

these equations are in slope-intercept form __ y=mx+b
__ where m is the slope of the line and b is the y-intercept

slope is the ratio of the change in y to the change in x
__ the "rise" divided by the "run"

the y-intercept is the point on the y-axis where the line crosses

the slope of the first graph is 4 __ a line parallel to it would have a slope of 4

the slope of the second graph is 2/7 __ a line parallel to it would have a slope of 2/7
