Does every line have a slope and a y intercept?

see below

Step-by-step explanation:

Not every line has a y intercept because vertical lines ( lines that go up and down) do not intersect the y axis

Does every line have slope?  It depends on how you define slope

Vertical lines have a slope that is undefined.  So they have a slope that is undefined.  When you are asked what the slope of a vertical line is , you answer undefined

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

the answer is d
