Question : The angle between the graph of the linear equation $239x-239y+5=0$ and the x-axis is:
Option 1: 0°
Option 2: 60°
Option 3: 30°
Option 4: 45°
Correct Answer: 45°
Solution :
Given: $239x-239y+5=0$
$\therefore$ Slope = $\frac{-239}{-239}$ = 1
So, $\tan\theta= 1=\tan 45°$
$\therefore\theta = 45°$
Hence, the correct answer is 45°.
