The slope of a line ST = 1. What is the value of y if S = (−5,−3) and T = (−1,y).

1 answer:

3 0

Step-by-step explanation:

$m = \frac{rise}{run} \\m = \frac{y2 - y1}{x2 - x1} \\ 1 = \frac{y - ( - 3)}{ - 1 - ( - 5)} \\ 1( - 1 + 5) = y + 3 \\ 4 - 3 = y \\ 1 = y$

Answer:

l = 24ft

Step-by-step explanation:

A = lw

360 = (x + 9)(x)

360 = x^2 + 9x

0 = x^2 + 9x - 360

0 = (x + 24)(x - 15)

x ≠ -24 (length cannot be negative)

x = 15

l = 15 + 9

l = 24ft
