B.y = x
C.y = 3x
D.y = - x
E.y = -6x
F.y = 6x

(help me understand this please)

Answer 1

Well you have to have a pic somewhere where the line(the graph) is represented. than you take 2 points for example x=1 and x=2 and substitude x and y(that you get from the line) and check which of the equations is the right one

Answer 2

The equation of the following line

A.y = 2x - the line has a slope of 2 and the line is rising to the right
B.y = x - the line has a slope of 1 and the line is rising to the right
C.y = 3x - the line has a slope of 3 and the line is rising to the right
D.y = - x - the line has a slope of -1 and the line is rising to the left
E.y = -6x - the line has a slope of -6 and the line is rising to the left
F.y = 6x the line has a slope of 6 and the line is rising to the right
