Answer:
equation of line m is x=3
equation of line n is y=-4
Step-by-step explanation:
Line m has no y intercept, and its x-intercept is (3,0).
When a line has no y intercept then it is a vertical line
for any vertical line the equation is x= x1
(3,0) is (x1,y1)
so equation of line m is x=3
Line n has no x intercept and its y -intercepts is (0-4).
When a line has no x intercept then it is a horizontal line
for any horizontal line the equation is y= y1
(0,-4) is (x1,y1)
so , the equation of line n is y=-4
