Question

1.

Which equation would represent the line with a slope of zero and the point (2,4)?

x = 2

x = 4

y = 2

y = 4

Answer 1

y=4. An "x=" line is a line with an undefined slope (a vertical line, to be exact). A line with a slope of 0 is a horizontal line, which is a "y=" line. Since, in our coordinate, the 4 is in the y place, the line has to be y = 4
