<span><u><em>Answer:</em></u>
y = 5x - 7

<u><em>Explanation:</em></u>
<u>The general form of the linear line in slope-intercept form is:</u>
y = mx + c
where:
m is the slope
c is the y-intercept

<u>1- getting the slope:</u>
The slope of the line can be calculated using the following formula:
m = </span>\frac{y_{2}-y_{1}}{x_{2}-x_{1}}
<span>
We are given the points:
(3,8) representing (x</span>₁<span>,y</span>₁<span>)
(2,3) representing (x</span>₂<span>,y</span>₂<span>)
Substitute with the givens in the above equation to get the slope as follows:
m = </span>\frac{3-8}{2-3}<span> = 5

<u>Therefore, the equation now became:</u>
y = 5x + c

<u>2- getting the y-intercept:</u>
To get the value of the c, we will use any of the given points, substitute in the equation we got in part 1 and solve for c. I will use point (2,3) as follows:
y = 5x + c
3 = 5(2) + c
3 = 10 + c
c = 3 - 10
c = -7

<u>Based on the above, the equation of the line is:</u>
y = 5x - 7

Hope this helps :)</span>

Answer:

y= 5x-7

Step-by-step explanation:

Using slope-intercept form:

The equation of line is given by:

y=mx+b                    .....[1]

where,

m is the slope of the line

b is the y-intercept.

As per the statement:

The points (3, 8) and (2, 3) fall on a particular line.

Using slope(m) formula:

m = \frac{y_2-y_1}{x_2-x_1}

Substitute the given points we have;

m = \frac{3-8}{2-3}=\frac{-5}{-1}=5

⇒m = 5

Put m = 5 in [1] we have;

y=5x+b

Substitute the point (3, 8) we have;

8 = 5(3)+b

8 = 15+b

Subtract 15 from both sides we have;

-7 = b

or

b = -7

Then we have;

y= 5x-7

Therefore, the equation of line in slope intercept form is, y= 5x-7

kenny6666 [7]

Answer:

16 feet in length.

Step-by-step explanation:

In this situation, you are given the area and the width of the full carpet, furthermore, you must reverse the formula for area to find the length, as so:

<u>Area Formula</u>: A=<em> l • w</em>

<u>Given</u>: 136= <em>l</em> • 8.5

<em>l</em> = 136 ÷ 8.5

<em>l</em> = 16 feet

Levant will receive about 9 american dollars when he exchanges his pesos.

According to this question, 1 american dollar is worth about 11 pesos. In order to find that, you need to divide 3000/270 which gives you around 11. In order to find out how many dollars he will receive for his pesos, you need to divide 100 by 11 which gives you about 9 dollars.
