Question

I need help with this, a better explanation and a clear answer :/

Answer 1

Since it is a line, the equation must be of the form:

`y=mx+b`

Let:

`\begin{gathered} (x1,y1)=(-5,-10) \\ (x2,y2)=(0,-1) \end{gathered}`

so:

`\begin{gathered} x=-5,y=-10 \\ -10=-5m+b_{\text{ }}(1) \\ ----------------- \\ x=0,y=-1 \\ -1=b \\ so\colon \\ -10=-5m-1 \\ -5m=-10+1 \\ -5m=-9 \\ m=(-9)/(-5) \\ m=1.8 \end{gathered}`

So:

`y=1.8x-1`

the most approximate option is:

`y=1.8x-1\approx2.097x-0.552`
