Also, what is the slope of a line whose graph is perpendicular to the graph of -6x+y=4?
-6x + y = 4
you can move the variables around to get the form: y = mx + b, which is the slope intercept form.
y = 6x + 4
here: m = 6, b = 4
m is the slope of the line, so slope is 6
any line parallel to this line will also have the slope of 6
any line perpendicular to the given line will have the slope of: -1/m1
we know m1 = 6, so the perpendicular line will have the slope of: -1/6
