Explain how the following ordered pairs represent or doesn't represent a function - {(-3, 5), (-2,5), (–1,5), (0, 5), (1, 5), (2,5)}

a. For every x value there is one y value - not a function
b. For every x value, there is one y value- a function
c. For every y value, there is one x value - function
d. For every y value, there is one x value - not a function

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Which graph represents the solution set for the given system of inequalities? x+2y< 3 x+y> 4 3x-2y> 4

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
