Answer:
is first one and last one 
Step-by-step explanation:
 
        
             
        
        
        
Y = x/4 - <span>€
y = (1/4)x - </span><span>€
</span><span>
y = 0.25x - </span>€   comparing to y = mx + c
m = slope = 0.25 or (1/4)
        
             
        
        
        
Answer:
Y=-4x+6
Step-by-step explanation:
Step 1: Add -x to both sides.
X+0.25y+-x=1.5+-x
0.25y=-x+1.5
Step 2: Divide both sides by 0.25.
0.25y/0.25=-x+1.5/0.25
Y=-4x+6
Hope I helped
