What is the equation of the line that passes through the points (3,-2) and (-1,2)

Mathematics

solmaris [256]3 years ago

Answer:

A. y = -x + 1

Step-by-step explanation:

First find the slope of the two lines using the slope formula: \frac{y_2-y_1}{x_2-x_1}.

\frac{2-(-2)}{-1-3} =\frac{4}{-4} =-1

Now use one of the two points; I am going to use (-1, 2).

Substitute the point and slope into the point-slope equation: y - y1 = m(x - x1).

y - (2) = -1(x - (-1))

Simplify.

y - 2 = -1x - 1

Add 2 to both sides and remove the 1 in front of the x. It is not needed.

y = -x + 1

a) We kindly invite to check the image attached below to see a detailed graph of the <em>piecewise</em> function.

b) The <em>piecewise</em> function is continuous.

<h3>How to understand a piecewise function</h3>

A <em>piecewise</em> function is a <em>conditional</em> combination of two or more functions, whose expression depends on which value of the domain is the function evaluated at.

a) The <em>piecewise</em> function described in the question is plotted on a graphing tool (i.e. <em>Desmos</em>), whose result is presented in the image attached below.

b) A function is <em>continuous</em> if and only if there is one value from range for every value of domain. The <em>piecewise</em> function is continuous as <em>linear</em> functions are continuous and the two functions of the <em>conditional</em> combination have the same value for x = 30.

The sales tax on a $150 DVD player is $6. What is the sales tax rate?
Goryan [66]
What percent of 150=6
X/100 * 150=6
/150. /150
X/100=0.04
X/100 *100/1 =0.04* 100/1
X=4
4% of 150=6

That means that for every dollar they take 4 cents from each dollar
150*4 pennies would equal 600 pennies or 6$ or 6.00
Hope this helps!

if jim is at his house and he is 30 miles away from his brothers house and he drives 25 miles an hour how long would it take for
sukhopar [10]
If Jim drives 25miles/hr and he is 30 miles away you would need to solve for the number of hours it would take to get there. So, you can set up a proportion: 25miles/1hr=30miles/xhr cross multiply to get 25x=30 divide both sides by 25 and your answer is 1.2 hours.
