Find the equation of the line that passes through points (4,5) and (-1,6).

steposvetlana [31]

First find the slope using the formula $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
Substitute the values in:
$m= \frac{6-5}{-1-4}= -\frac{1}{5}$
Point-slope form is $y=m(x-x_{1})+y_{1}$
Substitute (it doesn't matter which point you choose; I chose (4,5):
$y=- \frac{1}{5} (x-4)+5=-\frac{1}{5}x+\frac{29}{5}$
Therefore, the answer is D. $y=-\frac{1}{5}x+\frac{29}{5}$

6. What is the coordinates of the center and the radius of the circle

PtichkaEL [24]

Answer:

A. Center (4,3); Radius = 5 units

Step-by-step explanation:

The equation of a circle can be written in the form

(x-h)^2 + (y - k)^2 = r^2

where (h,k) is the center and r is the radius

(x-4)^2 + (y - 3)^2 = 25

(x-4)^2 + (y - 3)^2 = 5^2

The center is (4,3) and the radius is 5

Can someone help? ASAP!? (16 pts)

The coefficient of the variable is 3/8.

$\sf\dfrac{3}{8}(?+?)$

Divide 3/8 to each term to find out what goes in the parenthesis:

$\sf\dfrac{3}{8}b\div\dfrac{3}{8}=b$

So 'b' goes into the first spot in the parenthesis:

$\sf\dfrac{3}{8}(b+?)$

$\sf\dfrac{3}{4}\div\dfrac{3}{8}$

When dividing by fractions we flip(reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{3}$

Multiply:

$\sf\dfrac{24}{12}$

Divide:

$\sf 2$

This goes into the second spot in our parenthesis.

$\boxed{\sf\dfrac{3}{8}(b+2)}$
