1 answer:

4 0

Y = 3/4x + 2 [perpendicular: flip and change slope]

3 = -4/3 (6) + b
3 = - 8 + b
11 = b

ANSWER: D. y = -4/3x + 11

Answer:

Option A) Inside the circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The radius is equal to the distance from the center to any point on the circle

the formula to calculate the distance between two points is equal to

$d\sqrt{(y2-y1)^2+(x2-x1)^2 }$

we have

A(-5,-8),M(-1,-3)

substitute the values

$r=\sqrt{(-3+8)^{2}+(-1+5)^{2}}$

$r=\sqrt{(5)^{2}+(4)^{2}}$

$r=\sqrt{41}\ units$

step 2

Find the distance from the center to point V

we know that

If the distance from the center to point V is equal to the radius, then the point V lie on the circle

If the distance from the center to point V is less than the radius, then the point V lie inside the circle

If the distance from the center to point V is greater than the radius, then the point V lie outside the circle

we have

A(-5,-8),V(-11,-6)

substitute in the formula

$d=\sqrt{(-6+8)^{2}+(-11+5)^{2}}$

$d=\sqrt{(2)^{2}+(-6)^{2}}$

$d=\sqrt{40}\ units$

$\sqrt{40}\ units< \sqrt{41}\ units$

The distance from the center to point V is less than the radius

therefore

The point V lie inside the circle

Hope that helped :)

Find the slope of the line containing the two points. (2,5),(-3,-2) Please show work

HACTEHA [7]

Answer:

7/5

Step-by-step explanation:

To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)

The formula is:

$m= \frac{y{_2} -y_{1}}{x_{2}-x_{1} } \\\\$

So, we're going to use the points (2,5), (-3, -2) in this formula.

$m= \frac{-2-(5)}{-3-(2)} \\m=\frac{-2-5}{-3-2}\\m=\frac{-7}{-5} \\m=\frac{7}{5}$

Therefore, the slope is 7/5

Graph this equation y=7/2x-2

MariettaO [177]

To find the slope and y intercept, use the y=mx+b formula where m is the slope and b is the y intercept.
y=mx+b

Pull the values of m and b using the y=mx+b formula.
m=7/2,b=−2 where m is the slope and b is the y-intercept
