Answer:
D = 9.85 units
Step-by-step explanation:
A (1,7) and B(10,3)
Using Distance Formula to find the length
=> Distance Formula = ![\sqrt{(x2-x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2-x1%29%5E2%2B%28y2-y1%29%5E2%7D)
=> D = ![\sqrt{(10-1)^2+(3-7)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2810-1%29%5E2%2B%283-7%29%5E2%7D)
=> D = ![\sqrt{(9)^2+(-4)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%289%29%5E2%2B%28-4%29%5E2%7D)
=> D = ![\sqrt{81+16}](https://tex.z-dn.net/?f=%5Csqrt%7B81%2B16%7D)
=> D = ![\sqrt{97}](https://tex.z-dn.net/?f=%5Csqrt%7B97%7D)
=> D = 9.85 units (Upto 3 sfs)
Answer:
y = 3x + 2
y = 6x – 3
y = 2/3x + 6
y = –1/3x – 4
y = 2x + 1
Correct answer:
y = 3x + 2
Explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
