The given expression : y-1=2/3(x-3)
Simplify the equation :
for the graph we need atleast two coordinates
Let at x=0 then
y=2/3(0)-1
y=-1
Cooridnate = (0,-1)
Now, let x=9 then
y=2/3(9)-1
y=2(3)-1
y=5
Coordinate =(9,5)
Plot these point (0,-1) & (9,5)on the graph and join them by staright line
The graph will be ;
