The equation made from this is:
Let x = each 500 grams
Cooking time = 30x + 20
2.5 kg = 2500 grams
2500 / 5 = 5
X = 5
We put this in to the equation,
30*5 + 20 = 170 minutes
It will take 170 minutes to cook a joint of meat weighing 2.5 kilograms
Answer:

Answer:
y = 4x + 5
Step-by-step explanation:
y2 - y1/ x2 - x1
1 - (-3) / -1 - (-2)
4
y = 4x + b
13 = 4(2) + b
13 = 8 + b
5 = b
y = 4x + 5
