Answer:
The expression is equal to 
The area of the scale drawing is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
let
z------> the scale factor
x------> the area of the actual room
y-----> the area of the scale drawing
so
we have
substitute and solve for y
Answer:
slope = 3, point = (6, -2)
Step-by-step explanation:
This is in point-slope form which looks like this : y-y1 = m(x-x1).
m is the slope, an x1 and y1 are the x and y coordinates of the point. Remember to flip the sign of the numbers for the points i.e. the y+2 in the equation becomes -2 for the point.
Since we have a graph, we could see where '2' is on the x axis.
Since we see that 6 is where the functions value lies, that is the answer.
Answer: When x = 2, y = 6
