No, it does not pass through #(-2,-8)#, it passes through #(-2,10)#

assuming you mean 'Does the slope #-4x+2# pass through #-2,-8?'#

This is in the form #y=mx+c# where #y# is the #y# value, #m# is the gradient and #c# is the #y#-intercept.

As the coordinates the first coordinate represents the x value, we should substitute #-2# into the equation.

#x=-2#

#y=(-2 xx-4)+2=8+2=10#

#(-2,-8)# is NOT equal to #(-2,10#, therefore it does not pass through that coordinate
