Answer:
-7/4
Step-by-step explanation:
Slope is (y₂ - y₁) / (x₂ - x₁)
Using this, plug in the values they give.
(6 - (-1)) / (-4 - 0)
Simplify.
7 / (-4)
-7 / 4
The slope is - 7/4, or -1 3/4 ( negative 1 and three fourths)

-3, -1, and 1
-3 - 1 + 1 = -3
4*1= 4
4 - 7 = -3
Answer: 7,8,9
Step-by-step explanation:
Let the numbers be a, a+1 and a+2. Therefore, based on the question, this will be:
= (a + 1)(a + 2) = 72
a² + 2a + a + 2 = 72
a² + 3a + 2 - 72 = a
a² + 3a - 70 = 0
a² + 10a - 7a - 70 = 0
a(a + 10) - 7(a + 10)
a - 7 = 0
a = 7
Since a = 7
a + 1 = 7+1 = 8
a + 2 = 7+2 = 9
The numbers are 7,8 and 9
