Afunction is represented by the graph.
complete the statement by selecting from the drop-down menu.
the y-intercept of the function y=−2x+8y is the y-intercept of the function represented in the graph.
a graph with a line running through point (1,6) and point (5, -2)

Y = -2x + 8 The y intercept of the function is 8  

The equation that passes the point ( 1, 6 ) and ( 5, -2)
First solve the slope
M = ( 6 – (-2)) / ( 1 – 5 )
M = -2
At point ( 1,6) solve the y intercept b  
Y = mx + b
6 = (-2)(1) + b
b = 8
so the equation is   y = -2x + 8

The answer is 60.9774
