Hi,         

Graphing

f(x)= x+1     Pts (0,1), (-1,0), (1,2)

g(x)= -8x+10  PTs (0,10), (5/4,0), (1,2) 

Lines intersect at Pt(1,2), the solution for this system of equations

Note: when the lines intersect f(x) = g(x)

 x+ 1 = -8x + 10

   9x = 9

    x = 1  Substituting x=1 into either of the equations, will give

the same f(x) and g(x) value = 2, thus the Pt of intersection (1,2)
