complete the equation describing how x and y are related. x y -3 -25 -2 -18 -1 -11 0 -4 1 3 2 10 y = ?x + enter the number that belongs in the green box.
Answer
Explanation:
Step1: Recall the slope formula
The slope formula is (m=\frac{y_2 - y_1}{x_2 - x_1}). Let's take two points ((x_1,y_1)=(0,-4)) and ((x_2,y_2)=(1,3)).
Step2: Calculate the slope
Substitute into the formula: (m=\frac{3-(-4)}{1 - 0}=\frac{3 + 4}{1}=7).
