If m &lt; 0 and b &gt; 0, the graph of y = mx + b does not pass through which quadrant?
stiks02 [169]

Answer:

Quadrant III


Step-by-step explanation:

The attached picture shows graph of 4 such linear functions with the conditions given in the problem. ALL of them DO NOT pass through Quadrant III.

The graphs shown are of the functions:

y=-2x+1

y=-3x+3

y=-x+0.5

y=-5x+2


<em>So, any linear function of the form  y=mx+b  with  m  and  b>0  does not pass through Quadrant III. Answer choice 3 is correct.</em>
