First we try to frame the equation between the sale price and the final cost.
Let us consider, the price to be x and the final cost to be y, since the final cost is 75% of the price, we have the below equation
y = 0.75x
This is of the form of straight line equation y = mx +c where c =0 and m = 0.75
This means the function is linear since it satisfies a straight line equation.
So, we can eliminate options (3) and (4)
Now, the function is not a continuous one because the function is has definite value which is 0.75x and this make the function discrete. Hence option (2) is eliminated
Therefore we are left with option (1) which is the answer
Answer is (1) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant

I think those are the proper ratios
Answer:
The slope is 3/2
Step-by-step explanation:
The first step would be to find two clear points on the graph. You cant really get an exact reading on points between values so you want to get ones that are right on the mark.
On your graph I can clearly see the points (30,60) and (50,90).
From here you just use the formula to find the slope. ((y2-y1)/x2-x1))
90-60=30
50-30=20
30/20 can then be reduced to 3/2.
Hope this made sense!
