(17/2,16)- use the midpoint formula to find the midpoint of the line segment.
The total number of nails will decrease by 14 when Willa will use 7 nails on each side.
Step-by-step explanation:
Sides of one birdhouse = 7
Nails used on each side = 9
Nails used on one birdhouse = No. of sides * Nails used for each side
Nails used on one birdhouse = 7*9 = 63 nails
If she uses 7 nails on each side, then the number of nails used on each birdhouse will be;
No. of nails = 7*7 = 49 nails
Difference = Old value - New value
Difference = 63-49 = 14
The total number of nails will decrease by 14 when Willa will use 7 nails on each side.

Answer: y = 5x + 7</h3>
Work Shown:
y - y1 = m(x - x1)
y - (-3) = 5(x - (-2))
y + 3 = 5(x + 2)
y + 3 = 5x + 10
y = 5x + 10 - 3
y = 5x + 7
The equation is now in slope intercept form y = mx+b with m = 5 as the slope and b = 7 as the y intercept. Plugging x = -2 into this equation will lead to y = -3.
Side note: parallel lines have equal slopes but different y intercepts.
