Solution

We want to find the equation of the line given in the graph

We can see the four points on the graph where the line pass through

The points are


(4,4),(2,3),(0,2),(-4,0)

We first obtain the slope (m)

The formula for finding the slope is given as


m=(y_2-y_1)/(x_2-x_1)

Using the points (0,2) and (-4,0) (indeed we can pick any two points, we will still obtain the same answer)

Here


\begin{gathered} x_1=0 \\ y_1=2 \\ x_2=-4 \\ y_2=0 \end{gathered}


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(0-2)/(-4-0) \\ m=(2)/(4) \\ m=(1)/(2) \\ m=0.5 \end{gathered}

We can use any of the points above to find the equation

Equation of a line is given by


y-y_1=m(x-x_1)

Using (4,4)


y-4=0.5(x-4)

Option D is correct

Using (2,3)
