13. Line m has no y-intercept, and its x-intercept is (-5, 0). Line n has no x-intercept,

Lyrx [107]

Line m equation is $x+5 = 0$ .

Line n equation is $y+3 = 0$ .

Step-by-step explanation:

Here , we have Line m has no y-intercept, and its x-intercept is (-5, 0). Line n has no x-intercept, and its y-intercept is (0, 3). Let's find out equation of both line step by step:

Equation of line m:

Line m has no y-intercept , that means line is never intersecting y-axis which is only possible when line is parallel to y-axis , also this line have x-intercept as (-5,0) i.e. cuts x-axis at x = -5 .

⇒ $x = -5$

⇒ $x+5 = 0$

∴ Line m equation is $x+5 = 0$ .

Equation of line n:

Line n has no x-intercept , that means line is never intersecting x-axis which is only possible when line is parallel to x-axis , also this line have y-intercept as (0,3) i.e. cuts y-axis at y = 3 .

⇒ $y = -3$

⇒ $y+3 = 0$

∴ Line n equation is $y+3 = 0$ .
