Question

A line passes through (5, –4) and (–1, –4). Use the work below. m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction. M = StartFraction negative 4 minus (negative 4) Over negative 1 minus 5 EndFraction. M = StartFraction 0 Over negative 6 EndFraction. M = 0. What can you conclude about this line? Select all that apply. It is a vertical line. It is a horizontal line. The equation is x = –4. The equation is y = –4. It is impossible to have m = 0.

Answer 1

Answer:

It is a horizontal line

Step-by-step explanation:

1) any line with a slope of 0 is a horizontal line because even though the y coordinates are the same the x ones are different. Look at image one to get a deeper understanding of how a horizontal line looks:

Answer 2

Answer:

It is a horizontal line with equation: y = -4

Step-by-step explanation:

m = (-4 - (-4))/(-1-5) = 0/-6 = 0

m = 0

y = -4

It is a horizontal line
