Answer:

Option (A) is the correct answer.
Step-by-step explanation:

Now, 

∴ 
= 
= 
= 
Therefore option (a) is the correct answer.
1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.
y=mx+b
y=1/4x-5
2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1
Remember: in an ordered pair, x comes first then y.
Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9
6-(-)2/-2-9= - 4/11.
The slope of your next equation would be m= - 4/11
The answer would be negative 2.
-9+6=-3
List the numbers -3,-2,-1
The number in the middle is -2 and that is our answer.
