Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
Answer:
= 
Step-by-step explanation:
<u><em>Explanation</em></u>
Given

By using algebra formulas




= 

<u><em>Final answer:-</em></u>
= 
First factor the equation
(x-10)(x+2) = 0
Then solve for (x-10) and (x+2)
x=10
x=-2
Answer:
I'm taking an educated guess here and saying that its option two.
I haven't done these problems in almost two years.
hope this answer helps you dear...take care!
