115 = (4k+5) + (6k+10) when solving that, combine like terms. then use inverse operations.
That's a quadratic, a nice parabola in vertex form.
The parabola has a positive x^2 term, so it's a CUP, concave up positive. It will have a minimum at the vertex, which is (2,5). Plot that point.
Now we need a couple of guide points to draw the usual parabola going up from both sides of its vertex. We try x=0 giving (0,9) and see that x=4 also gives 9, (4,9). Plot the parabola through those two points and the vertex and you're done.

Answer:
y = 
Step-by-step explanation:
a) Let Area be the independent variable and Price of the homes sold be dependent on the area.
Let x represents the area and y represents the price.
We will plot the data in excel using trend line function.
The model so obtained is:
y =
Rounding values to the nearest hundredth, we get
y =
