What is the slope of the line of the best fit for this scatter plot?What is the equation of the line of the best fit?
Accepted Solution
A:
Answer:see explanationStep-by-step explanation:The equation of a line in slope- intercept form isy = mx + c ( m is the slope and c the y- intercept )Calculate m using the slope formulam = (y₂ - y₁ ) / (x₂ - x₁ )with (x₁, y₁ ) = (2, 7) and (x₂, y₂ ) = (4, 6) ← 2 points on the linem = [tex]\frac{6-7}{4-2}[/tex] = - [tex]\frac{1}{2}[/tex]Note the line crosses the y- axis at (0, 8) ⇒ c = 8y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line
