On a blue print every 1/4 inch is 1 ft what is the scale statement in the form of 1: x

1 inch: 4 ft

Step-by-step explanation:

We can use proportions to solve this problem.  Put the blue print size on the top and the real life size on the bottom.

1/4 inch         1 inch

 =

1 ft              x ft

Using cross products

1/4 * x = 1*1

Multiply each side by 4

4 * 1/4 *x = 4*1

x =4

1 inch: 4 ft

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
