Question

Graph the direct variation equation.
y=-1/2x

Answer 1

to graph a line, you need 2 points

Answer 2

plot 2 points, draw the line through them

Answer 3

A (the first graph)? @DanJS

Answer 4

hi, the thing for sure goes through the origin, if x=0, y is also 0

Answer 5

y = (-1/2)*x

is just the line equation , y = m*x + b
with b=0 and slope m=-1/2

Answer 6

the first graph has a positive slope

Answer 7

second graph has slope = rise/run = -2/1=-2
not -1/2

Answer 8

the last graph is y=-1/2 *x

every 2 increase oin x results in -1 decrease in y,

Answer 9

im confused now sorry. but D (the last graph) is -1/2??
