Question

what is the equation of the line that passes through (0, 2) and has a slope of 0? y = -2 y = 2 x = 2 user: what is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x y - 1 = 0? 2x - y - 4 = 0 2x y - 4 = 0 2x y 4 = 0 user: which of the following represents x = 1/2y written in general form? 1/2x - y = 0 2x - y = 0 x -1/2y = 0

Answer 1

correct answer would be Y = 2

Answer 2

y - 2 = 0(x - 0)
y - 2 = 0
y = 2

For parallel lines, slopes are equal. For line 2x + y - 1 = 0 => y = -2x + 1 => slope = -2
Required line = y - 2 = -2(x - 1)
y - 2 = -2x + 2
2x + y -2 - 2 = 0
2x + y - 4 = 0

x = 1/2y
2x = y
2x - y = 0
