Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown

y = 1/3 x
y = - 1/3 x + 4
y = 3x + 20
y = -3x - 16

Question

Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown

 y = 1/3 x 
 y = - 1/3 x + 4 
 y = 3x + 20 
 y = -3x - 16

How does that work if it's not one of the choices

anonymous · Answer

y = 3x + 20 
Look at the slope in the graph
the slope is 3/1 (up 3 and forward 1)
if it is parallel to another function, then it should have the same slope like y=3x+20

anonymous · Answer

It was B but I still got 80% thanks guys :)

yttrium · Answer

$$y = \frac{ -1 }{ 3 } (x+2)$$

anonymous · Answer

oh sorry I misread that, I thought it was asking for parallel -.-

It's all good
