On a coordinate plane, points (1, 2), (3, 6), and (5, 10) are plotted. Which characteristics tell you that this graph shows a pr
oportional relationship? Check all that apply. Three points are on the graph. A straight line can be drawn through the points. The ordered pairs all have the same x- and y-values. The line connecting the points passes through the origin.

From the diagram we have
Base =
Height =
Area = Base × Height
126 =
⇒ Expand the double bracket
126 =
⇒ Subtract 126 both sides
0 =
⇒ Factorise the quadratic expression
0 =
⇒ Equating each factor to zero
We need the positive value of
so we use
Height = 5+1 = 6
Base = 4(5)+1 = 21
Base =
Height =
Area = Base × Height
126 =
126 =
0 =
0 =
We need the positive value of
Height = 5+1 = 6
Base = 4(5)+1 = 21
