If the function f(x)= -1/2x-7 were graphed which of the following would be true

Graph by giving concrete values to x and then solve for f(x)

Simplify the formula of f(x)
f(x)=(-1/2)*x -7
f(x)=(-0.5*x) - 7 e.g. x = 1
then f(x) = (-0.5*1)-7 = -7.5

Put into table (minimum of 5 values of x)

f(x)=(-0.5*X/7)         Where X
       -6                           -2
       -6.5                        -1
       -7                            0
       -7.5                         1
       -8                            2

Graph this into a cartesian plane (x,y) plane you get the attached image.
we have p1(-2,-6), p2(-1,-6.5), p3(0,-7),p4(1,-7,5),p5(2,-8)
