Answer:
48 different houses can be designed from these plans.
Step-by-step explanation:
There are four options:
O1 - O2 - O3 - O4
O1 is the number of different living rooms. So O1 = 3.
O2 is the number of different bedroom configurations. So O2 = 4.
O3 is the number of different garage styles. So O3 = 2.
O4 is the number of different outside configurations. So O4 = 2.
In all,
48 different houses can be designed from these plans.
Answer:
a)
b)
c)
Step-by-step explanation:
a) The slope / gradient is the coefficient of , so for a) it will be
.
C is the y-intercept, so the full equation will be .
b) Again, since the slope is 6, we know the coefficient of will be 6.
Now, we have a point on the line and so far, we know the equation is . The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.
c) To find the gradient we must use the formula .
rise = change in y value
run = change in x value
so, the gradient
Now the equation is
Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).
so c) is
