Which equation represents the line shown in the graph below? A. y = -5/4 x B. y = 4/5x C. y= 5/4x D. y = -4/5x
Question
Answer:
Which answers cannot be.It has a minus slope.
That let's out B and C. They are both wrong. Minus slopes go from lower right to upper left.
How to find out which it is
Notice that x = 5 and y = -4 is on the given line
So you have two points (0,0) and (5,-4)
slope = (y2 - y1) / (x2 - y1)
slope = (-4 - 0)/ (5 - 0 )
slope = - 4/5
Line
y = - 4/5 x <<<< answer
