If the function f(x)= -1/2x-7 were graphed which of the following would be true
2 answers:
<span>Graph by giving concrete values to x and then solve for f(x)
Simplify the formula of f(x)
</span>f(x)=(-1/2)*x -7<span>
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)
</span>f(x)=(-0.5*X/7) <span>Where X
</span><span> -6 <span>-2
</span></span><span> -6.5 <span>-1
</span></span><span> -7 <span>0
</span></span><span> -7.5 <span>1
</span></span><span> -8 <span>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)</span></span>
