Answer:
The slope of this line is -2/7
Step-by-step explanation:
To find the slope between any two points, use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 1)/(-4 - 3)
m = 2/-7
m = -2/7
Answer:
$90
Step-by-step explanation:
The shoes now cost 130% of the original cost
The original cost is 100%
Take the new amount and divide it by 130:
117/130 = .90
Then multiply that number by 100 to get the original percent
.90 x 100 = $90
To check, multiply $90 by 130% or 1.30 to make sure that a 30% increase makes the product $117
$90 x 1.30 = $117
