Given:
[tex]7x-y=21[/tex]
Required:
To find the value of x-intercept and the y-intercept.
Explanation:
Consider the given equation,
[tex]7x-y=21[/tex]
To find x-intercept, set
[tex]y=0[/tex]
Thertefore, the given equation becomes
[tex]\begin{gathered} 7x-0=21 \\ 7x=21 \\ x=\frac{21}{7} \\ x=3 \end{gathered}[/tex]
Hence, the x-intercept is 3.
To find y-intercept, set
[tex]x=0[/tex]
Therefore,
[tex]\begin{gathered} 7(0)-y=21 \\ -y=21 \\ y=-21 \end{gathered}[/tex]
Final Answer:
The x-intercept is 3.
And the y-intercept is -21.
