Question

The graph below shows two functions:

function f of x is a straight line which joins the ordered pairs negative 2.8,16 and 3.5, negative 2.5. Function g of x is a curved line which joins the ordered pairs negative 1.9, 13.5 and 2.6, 0

Based on the graph, what are the approximate solutions to the equation –3x + 8 = (0.25)x?

1.9 and –2.6
8 and 2.6
1 and 2.6
–1.9 and 2.6
