The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is y + 7 = (x – 10). What is the stan
torisob [31]

The point slope form of the line which passes through the points (-5,-1) and (10,-7) is \fbox{\begin\\\ \math 2x+5y=-15\\\end{minispace}} i.e., \fbox{\begin\\\ \bf option C\\\end{minispace}}.

Further explanation:

It is given that line passes through the points (-5,-1) and (10,-7).

The objective is to determine the point slope form of the line which passes through the points (-5,-1) and (10,-7).

The options given are as follows:

Option A: 2x-5y=-15

Option B: 2x-5y=-17

Option C: 2x+5y=-15

Option D: 2x+5y=-17

Consider the point (-5,-1) as (x_{1},y_{1}) and (10,-7) as (x_{2},y_{2}).

Slope of a curve is defined as the change in the value of y with respect to change in value of x.

The slope of the line is calculated as follows:

\fbox{\begin\\\ \math m=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\end{minispace}}

To obtain the value of slope substitute the value of x_{1},y_{1},x_{2},y_{2} in the above equation.

\begin{aligned}m&=\dfrac{-7-(-1)}{10-(-5)}\\&=\dfrac{-6}{15}\\&=\dfrac{-2}{5}\end{aligned}

Therefore, the slope of the line is \fbox{\begin\\\ \math m=\dfrac{-2}{5}\\\end{minispace}}

The general way to express the equation of a line in its point slope form is as follows:

\fbox{\begin\\\ \math (y-y_{1})=m(x-x_{1})\\\end{minispace}}

To obtain the point slope form of the equation of the line substitute the value of m, x_{1} and y_{1} in the above equation.

\begin{aligned}(y-(-1))&=\dfrac{-2}{5}(x-(-5))\\(y+1)&=\dfrac{-2}{5}(x+5)\\5y+5&=-2x-10\\5y+2x&=-15\end{aligned}

From the above calculation it is concluded that the point slope form the equation of a line is \fbox{\begin\\\ \math 5y+2x=-15\\\end{minispace}}

Figure 1 (attached in the end) represents the graph of the function 5y+2x=-15.

This implies that the correct option for the point slope form of the line is option C.

Therefore, the point slope form of the line which passes through the points (-5,-1) and (10,-7) is 2x+5y=-15 i.e., option C.

Saige's spaceship traveled 588588588 kilometers (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis i
lesantik [10]

Answer:

A is proportional

B and C are <u>NOT</u> proportional

Step-by-step explanation:

First, simplify 588 and 60:

<u>588 divided by 6</u>

60 divided by 6

= <u>98</u>

  10

Simplify them again by dividing them both by 2

= <u>49</u>

   5

Let's look at A:

441 and 45

Simplify by dividing by 9

= <u>49</u>

   5

It's pretty obvious that A is <u>proportional</u> because the simplified values are exactly the same.

Next, let's check B:

215  and 25

Simplify by dividing by 5

= <u>43</u>

   5

Now that its simplified you can compare

<u>43</u>   is smaller than <u>49</u>

5                               5

B is <u>not proportional</u>

<u />

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= <u>51</u>

  10

Make <u>51</u> and <u>49</u> have the same denominator so we can compare them

          10         5

<u>51</u> can stay the same because 5 times 2 equals 10

10

<u>49 times 2</u>

5 times 2

=  <u>98</u>

    10

Now that the denominators are the same we can compare

<u>51</u> is much smaller than <u>98</u>

10                                     10

Therefore, C is also <u>not proportional.</u>

<u />

Hope that helps :D

<u />
