Then, -77 = m*8+35 ( as the graph passes through the point ( 8 , -77)
8m= -77-35 = -112
Hope its clear.
The graph of the relation y=mx+35 passes through the point (8,-77). Determine the value of m.
First place the values in the point in to the equation.
(X,Y) is (8,-77)
so y=mx+35 is -77=m8+35
then isolate the variable by subtacting 35 from both sides
now divide both sides by 8
I hope this clears this up for you.
