General equation of line is:

(a)

Where c represent y intercept then the value of c is zero.

so equation is:

Where m represent the slope.

$m=\frac{y_2-y_1}{x_2-x_1}$

Pick two point from graph .

$\begin{gathered} (20,10) \\ (10,5) \end{gathered}$ $\begin{gathered} m=\frac{10-5}{20-10} \\ m=\frac{5}{10} \\ m=\frac{1}{2} \end{gathered}$

$y=\frac{1}{2}x$

this equation represent this graph.

(c)

The equation of line is straight line so graph title is straight line.

(d)

At x=30 then the coordinates of graph is:

(b)

Lebel the axes is

That mean value of y is double .
