Answer:
The solution is (0, 4)
Step-by-step explanation:
Please pay attention to the first two equations and drop the last two:
12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:
12x−5y=−20
y=x+4
Let's find x. Substitute x + 4 for y in the first equation, obtaining:
12x - 5(x + 4) = -20
Carrying out the indicated multiplication, we get:
12x - 5x - 20 = -20, or 7x = 0
If x = 0 then y must be 0 + 4, or 4.
The solution is (0, 4)
Answer: the slope is 0
Step-by-step explanation: hope it helps
Answer:
D
Step-by-step explanation:
Just took it.
So the equation we are working with is y=mx +b. If you use the distance formula, you will find the slope. The slope is 1/2 and the y intercept is 0. your equation is y=1/2x. So plug in the point that it gives you.
-2 is your y value.
so it will look like this: (x could also be n)
-2=1/2x...solve....n=-4
The distance between two points is given by:
d² = (x₂-x₁)² + (y₂ - y₁)²
9 = (x₂ - 4)² + (y₂ - 2)²
Now, we can check different ordered pairs in this equation to see which satisfies it:
The one that satisfies this equation is (4 , -1).
