Answer:
For me when I am finding the slope I actually use the slope formula .
Step-by-step explanation:
Step 1 you have to find the x and y
Step 2: Use the slope formula
Step 3: Subtract y2 and y1 to get your answer
Step 4: Subtract x2 and x1 to get your answer
Step 4: If your answer is easy to divide simplify it, if not leave it as it is
That's all I know
I hope this helps :)
Answer: She has walked 9/20 miles in total
Step-by-step explanation:
1/5*4=4/20
1/4*5=5/20
4/20+5/20=9/20 miles

Answer: (x,y) = (4,1)</h3>
In other words, x = 4 and y = 1
==============================================
Explanation:
Add the equations straight down.
- The x terms add to 3x because 2x+x = 3x
- The y terms go away when you add them since -y+y = 0y = 0
- The terms on the right hand sides add to 7+5 = 12
After those three sets of adding terms, we end up with 3x = 12. This solves to x = 4 when you divide both sides by 3.
Use this x value to find y.
2x-y = 7
2(4)-y = 7
8-y = 7
-y = 7-8
-y = -1
y = 1
or
x+y = 5
4+y = 5
y = 5-4
y = 1
Your best best is probably to use the second equation, but it doesn't hurt to have practice with both equations. Getting the same y value helps confirm we have the correct x value.
Therefore, the solution is the ordered pair (x,y) = (4,1). Meaning that x = 4 and y = 1 pair up together.
Visual confirmation can be done by using a graphing tool like Desmos. The two lines intersect at (4, 1). See below.
