The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have two points (2, 0) and (-2, -4). Substitute:
Therefore we have the equation of a line
Put the coordinates of the point (2, 0) to the equation:
<em>subtract 2 from both sides</em>
Answer: 
Answer: C
Step-by-step explanation: since he has 4 dice, there are 24 chances. But he needs 2 fives. That means 2/24 = 1/13. 1/13= C
Answer:
-0.25, -0.15, -0.6
Step-by-step explanation:
- 1/4= -0.25.
Bigger number with negative = smaller number
Answer: Direction opens downward
Step-by-step explanation:
X-Intercept: (1/14,0),(-1/4,0)
Y-Intercept: (0,1)
Find the vertex using x= -b/2a
Plug it into the vertex form = y=a(x-h)^2 +k
H,K will identify the direction.

If both binomials have the same variables to the same powers, then it is true. In general, multiplying binomials gives four terms, one corresponding to each letter of the FOIL acronym. So, you only get a trinomial when the O and I terms combine.
