Question
Graph line $$ y = 25 x - 20 $$
Solution
The given equation is:
$$ \color{blue}{ y = 25 x - 20 } $$To draw the graph we will find y-intercept and x-intecept.
To find y - intercept we substitute $ \color{blue}{x = 0} $:
$$ \begin{aligned} y &= 25 x - 20 \\y &= 25 \cdot \color{blue}{0} - 20\\y &= -20 \\\end{aligned} $$To find x - intercept we substitute $ \color{blue}{y = 0}$:
$$ \begin{aligned} y &= 25 x - 20 \\\color{blue}{0} &= 25 x - 20\\x &= \frac{ 4 }{ 5 }\end{aligned} $$So, the graph of the equation is:
