The slope is 3.
10 - 7 = 3
4 - 3 = 1
Final step is to do 3 divided by 1 and you get 3.
Did you ever get the answer to this?
Answer:
B. y-7 = 1/2(x+3)
Step-by-step explanation:
The coordinates in the question must be inverted (so -3 would become +3 and +7 would become -7)
We know that the line would be perpendicular when (x+3) is preceded by -2
You can double check this by going to a website that graphs equations and overlapping the lines.
Answer:
I think that 12 feet is equal to 4 yards
Hello!
To solve this problem, we will use a system of equations. We will have one number be x and the other y. We will use substitutions to solve for each variable.
x+y=9
x=2y-9
To solve for the two numbers, we need to solve the top equation. The second equation shows that x=2y-9. In the first equation, we can replace 2y-9 for x and solve.
2y-9+y=9
3y-9=9
3y=18
y=6
We now know the value of y. Now we need to find x. We can plug in 6 for y in the second equation to find x.
x=2·6-9
x=12-9
x=3
Just to check, we will plug these two numbers into the first equation.
3+6=9
9=9
Our two numbers are three and six.
I hope this helps!
