m = #6#

x-intercept = #(-1/6,0)#

y-intercept = #(0,1)#

#color(blue)"Slope"# = #color(blue){(rise)/(run)}#
Since 6 is essentially #6/1# we know that the slope goes up 6 units

and right 1 unit on a graph.

Next, #color(blue)"to find the y-intercept"# of y=6x+1, you substitute x as x=0."#

#y=6x+1#

#y=6(0)+1#

#y=1#

#:.# the y-intercept is 1 when x is 0 thus #(0,1)#

#color(blue)"To find the x-intercept"# of y=6x+1, you let y=0.

#y=6x+1#

#0=6x+1#

#0-1=6x#

#-1=6x#

#x=-1/6#

#:.# the x-intercept is -1/6 when y is 0 thus #(-1/6,0)#
