Plssss i need help rn ​
wariber [46]

Answer:

3

Step-by-step explanation:

(x₁ , y₁) = (-1 , -2)   &    (x₂ , y₂) = (3 , 10)

Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         = \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4

m  = 4

y - y₁ = m (x - x₁)

y - [-2] = 4(x - [-1])

y + 2 = 4(x + 1)

y + 2 = 4x + 4

    y = 4x + 4 - 2

    y = 4x + 2

Change = 25.004 - 24.85

= 0.154

So, the required change in the price is equal to 0.154 .
