Because change in y for the rise is if it goes up or down and change in x for the run to see if it goes left or right
I hope this helps you
slope=y2-y1/x2-x1
slope=2-(-1)/1-2
slope=3/-1
slope= -3
Answer:
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
Step-by-step explanation:
First we will find out how many meters 3 feet will be.
1 feet = 0.3048 meters
She needs 3 feet of fabric
3 *1 feet = 3* 0.3048 ( multiplying both sides by 3)
3 feet = 0.9144 meters
Using the unitary method we will find the cost of 3 feet of fabric
1 meter costs $ 1.20
0.9144 *1 meter costs $ 1.20 * 0.9144 ( multiplying both sides by 0.9144)
0.9144 meter = $ 1.09728
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
