jillian recorded how much fertilizer she gave her roses and the number of blooms they produced. what is a good line of best fit for the data?\na y - 8 = 1(x - 4)\nb y - 8 = -1(x - 4)\nc y - 8 = \\frac{4}{3}(x - 4)\nd y - 8 = -\\frac{4}{3}(x - 4)

Answer

Answer:

A. $y - 8=1(x - 4)$

Explanation:

Step1: Observe data trend

The number of blooms increases as fertilizer amount increases, so slope is positive.

Step2: Analyze point - slope form

The point - slope form is $y - y_1=m(x - x_1)$. Positive slope eliminates B and D.

Step3: Estimate slope visually

The data seems to have a slope close to 1, so A is a good fit.
