Exercises: Intersection of two lines

Determining the intersection point

Set $f(x)$ and $g(x)$ equal.

${\mathrm{x}}_S=50$

Plug x into one of the two function equations.

$\Rightarrow S(x_S;y_S)=S(50;22.5)$

$S$ is the intersection point.

Sketch

Connect the $y$-axis intercepts (here $A$ and $B$) with the calculated intersection point $S$ to obtain the lines.
