Question : Find the coordinates of the points where the graph $57x – 19y = 399$ cuts the coordinate axes.

Option 1: x-axis at(–7, 0) and y-axis at (0, –21)

Option 2: x-axis at(–7, 0) and y-axis at (0, 21)

Option 3: x-axis at (7, 0) and y-axis at (0, –21)

Option 4: x-axis at (7, 0) and y-axis at (0, 21)

Team Careers360 · Accepted Answer

Correct Answer: x-axis at (7, 0) and y-axis at (0, –21)

Solution : $57x-19y=399$
⇒ $\frac{57x}{399}-\frac{19y}{399} = 1$
⇒ $\frac{x}{7}-\frac{y}{21} = 1$ -------------(i)
Comparing it with the equation of a line:
$\frac{x}{a}+\frac{y}{b} = 1$
x-intercept = $a$ = 7
y-intercept = $b$ = –21
The line, $57x-19y=399$, cuts the x-axis at (7, 0) and the y-axis at (0, –21)
Hence, the correct answer is 'x-axis at (7, 0) and y-axis at (0, –21)'.
