It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
2x2 – 5x<span> – 3
thats the answer. </span>
2(5*4)+2(4*3)+2(3*5)=94 sq.m (Orginial SA)
2(4*5)+2(5*6)+2(6*4)=148 sq.m (Total SA)
148-94=54 (New SA)
Answer: y = x^2 - 2 does not represent a linear function because the squared exponent above the variable makes that equation quadratic. Quadratic equations look like parabolas on a graph, rather than lines.
the are would be 64 inches pi or approximately 200.96 inches squared
Hope this helps!
