How do you graph #y= 4x-5#?

This is the form #y=mx+b#

Where #mx# is the slope and the #b# value is the y-intercept

First plot the #b# value in this case it is -5

Then from that point #(0,-5)# use the slope to find the other points

#Slope=(rise)/(run)#

Rise translates to the amount of units "up or down" you go

Up = Positive
Down = Negative

Run translates to the amount of units "left or right" you go

Left = Negative
Right = Positive

So starting from the point #(0,-5)# go up 4 units and right 1 unit or down 4 and left 1 unit since they both make the slope of 4 --> #(4/1) and ( -4/-1)#
