Answer:

Step-by-step explanation:
Given that,
A line goes through the point (-8,9), and has a slope of 3/4.
We need to express in the form of Ax+B for this line.
We have, m = 3/4
So,

Put y = 9 and x = -8 in the above equation.

So,

It is the required equation of the line.
Answer:
The real perimeter is:

And the area would be:

Step-by-step explanation:
For this case we know one side of a square given 6mm.
We can begin calculating the perimeter for the scale figure with this formula:

The area for this case is given by:

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

And the area would be:

10=5×2 or 5×2=10 or 2×5=10 or 10=2×5
they're all the same thig but i'd probably go with 5×2=10 :)
