Answer:
Step-by-step explanation:to find the proportionlity it has to go through the origin (0,0) and has to be a straight line on a graph but, in a model label your measurements as x1 ,y1 ,x2, y2 because y2-y1/x2-x1 should give u a answer then do y/x
Answer: 7/21 is the answer because 7 * 2 = 14 and 21*2=42
Step-by-step explanation:
zero
they are parallel once graphed
Infinitely many solutions
2y=14-2x
y=-x+7
------------
2(-x+7)=14-2x
-2x+14=14-2x
-2x-(-2x)=14-14
-2x+2x=0
0=0
infinitely many solutions
2^4 x 2^-7 = 0.125
2^3 = 8, 1 /8 = 0.125
answer is B
