HELP ME FAST PLEASE

Step-by-step explanation:

from what I can see, the line goes through (100, 0) and (0, -100).

the general line function is

y = ax + b

a is the slope of the line, excised as ratio y/x, as it indicates how many units y changes, when x changes a certain amount of units.

we use the 2 points to find the coordinate differences and therefore the slope.

going from (0, -100) to (100, 0) x changes by +100, and y changes by +100.

so, the ratio y/x = a = 100/100 = 1

now to find b we use the coordinates of one of the points in the main equation and solve for b. we use e.g. (100, 0)

0 = 1×100 + b

b = -100

so, the line function is

y = x - 100

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
