A square has 4 right angles and 4 equal sides.
If you draw a diagonal through the square then you get two right triangles. So the area relation between a square and a right triangle is going to be half. The area of the triangle is half the area of the square.
Also the formula for area of a square is length times width.
And the formula for the area of a right triangle is 0.5 times length times width.
So if you set up the equation (let's use * as multiplication symbol ):
Area of a Square : Area of a Right Triangle
length * width : 0.5 * length * width
(Divide by length * width on both sides)
1:0.5 or 2:1
A 150% markup of a picture frame that costs 2.99 would cost : 4.49
2.8 or if rounded to the nearest tenth so 2.8√8
Okay, so here, we know that -10 is the slope, therefore, it is also the constant of proportionality.
'x' is the unknown value, that tells us to multiply by -10.
So, on a graph, we would consider that per unit, it would decrease by -10, since its a negative slope.
