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

Rachel and her friends are making necklaces out of beads and straws. They plan to use 12 beads and 5 straws for each necklace. T

Answer:

225 necklaces.

Step-by-step explanation:

Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.

t = b/12 ... where t is the total amount of necklaces and b is the number of beads you have

t = 2700 / 12

225 necklaces.

For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.
