Question

Find two points on the line to graph the function Any lines orCurves will be drawn once all required points are plotted

Answer 1

A: (4, 9)

B: (-1, -3)

Explanation:

We have the following function:

`q(x)=4x-((3+8x))/(5)`

We determine the two points when x = 4 and when x = -1, like this:

`\begin{gathered} q(4)=4\cdot4-(\left(3+8\cdot4\right))/(5)\: \\ \\ q(4)=16-(3+32)/(5)=16-7 \\ \\ q(4)=9 \\ \\ A=(4,9) \\ \\ q(-1)=4\cdot\left(-1\right)-(\left(3+8\cdot(-1)\right))/(5)\: \\ \\ q(-1)=-4-(3-8)/(5) \\ \\ q(-1)=-4-(-1)=-4+1 \\ \\ q(-1)=-3 \\ \\ B=(-1,-3) \end{gathered}`

Therefore point A is (4, 9) and point B is (-1, -3)
