Answer:
0.75 or 3/4 boxes of nails per bird house
Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
Answer:
I'm pretty sure the length would have to be 8 cm too. Basic logic.
Step-by-step explanation:
Hi
-6 /7 = -x / 84
Cross multiply
-7x = -6 * 84
-7x = -504
x = -504/-7
x = 72
