Answer:
Step-by-step explanation:
Given the system of equations:
2x + 3y = 15
X + 3y = 0
What is x?
2x + 3y = 15
X + 3y = 0 subtract the bottom equation fron the top one
2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero
2x - x = 15
x = 15 Now for extra credit what is y?
X + 3y = 0
15 + 3y = 0
15 - 15 + 3y = 0 - 15
3y = -15
3y/3 = -15/3
y = -5
-15

Answer:
(4,7) up 3 units and right 6 units is (10,10)
Step-by-step explanation:
(4,7) goes up 3 units, which becomes (4,10). (Go up: 7 + 3 = 10)
(4,10) moves to the right 6 units, which becomes (10,10). (Right: 4 + 6 = 10)
Hey there!
You can find the slope by using this equation:
It doesn't matter what order you use the points in as long as the x's and y's are in the right place.
Just plug your numbers into the equation and solve.
The slope is –1.
Hope this helped you out! :-)
