Answer:
Proportionality equation: 
Linear equation: 
Step-by-step explanation:
So the amount that Cameron earns = 7/hr
Hours = x
And total earned amount = y
So we can form an equation from this for the total amount:

But the question asks us for a proportionality equation so:
Proportionality constant = k
So we get the equation:

The rate of change is equal to the slope of a line. Given any 2 points on a line and you can calculate the slope (rate of change) of that line. The formula for rate of change is given by Δy/Δx which equals (y2-y1)/(x2-x1). Therefore, using the points given in the question and simply input them into our formula, we get ((4)-(3))/((-2)-(0)) = -1/2

Answer:
18.6cm
Step-by-step explanation:
there is a theorem that states that the midsegment of a triangle (midpoint to midpoint, in this case X and Y) is half of the base (in this case BC)
when applied to the triangle shown:
XY= 1/2 BC
substitute to get
XY=1/2*6.4
XY=3.2
perimeter of BCYX
=XY+YC+CB+BX
=3.2+4+6.4+5
=18.6cm
hope this helps
