Answer:
x=3
Step-by-step explanation:
When you substitute x = 3 to both equations, you get y = -4 for both so that is a solution
Answer:
180-140=50 180-90-50= 40 m=40
39 and 36. both of them rounded to the nearest 10 is 30
Answer:
6
+ 6m -9
=> (6
- 9
) + 6m
=> -3
+ 6m

Thank You!!
The slope-intercept equation is y=mx+b.
The slope formula is 
Our three points are (5,5), (-5,-7) and (0,-1)
Using our slope formula our slope becomes 
Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So,
. When we solve for x and y, we get -1=0+b, or b=-1.
When we plug that back into the equation, we get
.
