Answer:
AB ≈ 6.71
Step-by-step explanation:
Calculate the length using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = A (- 1, 6) and (x₂, y₂ ) = B (5, 3)
AB = ![\sqrt{(5-(-1))^2+(3-6)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%285-%28-1%29%29%5E2%2B%283-6%29%5E2%7D)
= ![\sqrt{(5+1)^2+(-3)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%285%2B1%29%5E2%2B%28-3%29%5E2%7D)
= ![\sqrt{6^2+9}](https://tex.z-dn.net/?f=%5Csqrt%7B6%5E2%2B9%7D)
= ![\sqrt{36+9}](https://tex.z-dn.net/?f=%5Csqrt%7B36%2B9%7D)
= ![\sqrt{45}](https://tex.z-dn.net/?f=%5Csqrt%7B45%7D)
≈ 6.71 ( to 3 significant figures )
Answer:
top right
Step-by-step explanation:
it cannot be the bottom ones and the top left one is showing 2x-1 which is not either of the equations
Answer:
Step-by-step explanation:
If you want to find the equation of line with a given a slope of which goes through the point (-4,5), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
where is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
Plug in , , and (these values are given)
Distribute
Multiply and to get
Add -1 to both sides to isolate y
Combine like terms and to get the answer
So the equation of the line with a slope of which goes through the point (-4,5) is:
which is now in y=mx = b form where the slope is m=-4/5 and the y-intercept is b=1
Answer:
your answer will be
y=40 x +20
