Answer:
![dAB=10\ units](https://tex.z-dn.net/?f=dAB%3D10%5C%20units)
Step-by-step explanation:
we know that
The <u>distance formula</u> is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points
The formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have
A(1, 1) and B(7, −7)
Let
(x1,y1)=A(1, 1)
(x2,y2)=B(7, −7)
substitute the given values in the formula
![dAB=\sqrt{(-7-1)^{2}+(7-1)^{2}}](https://tex.z-dn.net/?f=dAB%3D%5Csqrt%7B%28-7-1%29%5E%7B2%7D%2B%287-1%29%5E%7B2%7D%7D)
![dAB=\sqrt{(-8)^{2}+(6)^{2}}](https://tex.z-dn.net/?f=dAB%3D%5Csqrt%7B%28-8%29%5E%7B2%7D%2B%286%29%5E%7B2%7D%7D)
![dAB=\sqrt{64+36}](https://tex.z-dn.net/?f=dAB%3D%5Csqrt%7B64%2B36%7D)
![dAB=\sqrt{100}](https://tex.z-dn.net/?f=dAB%3D%5Csqrt%7B100%7D)

Answer:
B) m = 2 , b = -3
Step-by-step explanation:
b = y-intercept
The y-intercept is -3
b = -3
m = slope
The slope is 2
m = 2
hi
if x= 2+4y-5 then x-2 +5 = 4y so y = (x-2+5) /4 = ( x+3) /4
conclusion y = (x+3)/4
