16-8
Final Answer: 8
To find slope, pick any 2 points and use formula: (y2-y1)/(x2-x1)
2 points on line: (4,0), (0,-2)
(-2-0)/(0-4) = -2/-4 = 1/2
a) the slope is 1/2
Y = 1/2x + b
0 = 1/2(4) + b
0 = 2 + b, b = -2
b) -2 is the y intercept
Put the equation together
c) y = 1/2x - 2
Um okay.
Also, I think it'll be A.
Answer:
72 inches!
Step-by-step explanation:
