Write y=mx+b in the intercept form then list the x and y-intercepts.

Sagot :

Answer::

[tex]\begin{gathered} y-\text{intercept}=b \\ x-intercept=-\frac{b}{m} \end{gathered}[/tex]

Explanation:

The intercept form of the equation of a line is given as:

[tex]\frac{x}{a}+\frac{y}{b}=1[/tex]

Given the equation:

[tex]y=mx+b[/tex]

We have:

[tex]\begin{gathered} y-mx=b \\ \text{Divide both sides by b} \\ \frac{y}{b}-\frac{mx}{b}=\frac{b}{b} \\ -\frac{mx}{b}+\frac{y}{b}=1 \\ \frac{x}{-\frac{b}{m}}+\frac{y}{b}=1 \end{gathered}[/tex]

Therefore, the x and y-intercepts are given below:

[tex]\begin{gathered} y-\text{intercept}=b \\ x-intercept=-\frac{b}{m} \end{gathered}[/tex]
