How would you figure out what coordinate B is?

Answer:
B = (4, 0)
Step-by-step explanation:
We are told that [tex]l_2[/tex] intersects the x-axis at B.
To determine where [tex]l_2[/tex] intersects the x-axis, set y to zero in the [tex]l_2[/tex] equation and solve for x:
[tex]\implies 0+x=4[/tex]
[tex]\implies x=4[/tex]
Therefore, B is (4, 0)
Answer:
(4,0)
Step-by-step explanation:
coordinate B lies on the equation y + x = 4
y = 0 and x is unknown, so putting this in the equation:
y + x = 4
0 + x = 4
x = 4
