Write a in slope-intercept form of the line that passes threw (-9,5) and (-3,3)

Amanda [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

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

We have the following points:

$(x_ {1}, y_ {1}): (- 9,5)\\(x_ {2}, y_ {2}): (- 3,3)$

Substituting we have:

$m = \frac {3-5} {- 3 - (- 9)}\\m = \frac {-2} {- 3 + 9}\\m = \frac {-2} {6}\\m = - \frac {1} {3}$

Thus, the equation is of the form:

$y = - \frac {1} {3} x + b$

We substitute one of the points and find "b":

$3 = - \frac {1} {3} (- 3) + b\\3 = 1 + b\\3-1 = b\\b = 2$

Finally, the equation is of the form:

$y = - \frac {1} {3} x + 2$

Answer:

$y = - \frac {1} {3} x + 2$

Kayte wants to buy a new sled she has already save 35% of them out she needs what fraction describes this percent

e-lub [12.9K]

In order to find what fraction describes this percentage, you first need to know that no matter what percentage you are working with, if you want to convert it into a fraction, put the 35 as the numerator and 100 as the denominator. If you still don't know what I mean, 35 at the top of the fraction and 100 at the bottom. Like this; 35/100. Then, you can simplify it by finding a common multiple between 35 and 100. For example, 5 can be divided into 35 and 100. 35 divided by 5 is 7 and 100 divided by 5 is 20. Your result is 7/20, which can further no more be simplified because there are no more common multiples between the two numbers.

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?

victus00 [196]

Answer: Choice C. p = 250(0.79)^t

Work Shown:

p = a*b^t

p = a*(1+r)^t

p = 250*(1+(-0.21))^t

p = 250(0.79)^t

Note that r = -0.21 is negative to indicate we have exponential decay.

What is the midpoint of the segment shown below?

RSB [31]

Answer:

Step-by-step explanation:

The mid point of the line segment is defined as the point on that line that divides the line segment in to two congruent segments and is denoted as:

Mid point= $(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

Now, the line segment having the points (-2,4) and (6,-4) has the mid point:

Mid point= $(\frac{-2+6}{2},\frac{4-4}{2})$

= $(2,0)$

Hence, the mid point of the given line segment is: (2,0)

Therefore, Option C is correct.
