The graph below shows two functions:

function f of x is a straight line that joins the ordered pairs negative 2.8, 16.4 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
