Question

Line H is represented by the following equation:

Answer 1

To have infinite points the lines have to be the same.
If you divide every term in the example by 2
You get x+y=4

Answer 2

Answer:

b. x + y = 4

Step-by-step explanation:

For to lines to have an infinite number of points that intersect, the lines have to have the exact same equation, so that every coordinate of H and K is the exact same.

Simplify the equation for H:

$2x+2y=8\\2y=8-2x\\y=4-x$

Rearrange the equation:

$x+y=4$
