3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4

mafiozo [28]

Step-by-step explanation:

$slope \: = \frac{y2 - y1}{x2 - x1} = \frac{3}{4}$

point 1 ( -7,y)

point 2 (1,13)

$\frac{13 - y1}{1 - ( - 7)} = \frac{3}{4}$

$\frac{13 - y1}{8} = \frac{3}{4}$

$13 - y2 = \frac{8 \times 3}{4} = 6$

$y2 = 13 - 6 = 7$

y = 7

Due to a special, the jeans are reduced to 80% of their original price. This means that the original price was reduced by 20%. Therefore, the current price, x would be

x = 15 - (20/100 × 15) = 15 - 3

x = $12
