Explain weather this equation is a linear equation <br> 4. y = 1 - x
sergey [27]

Answer:

Yes, it is a linear equation.

Step-by-step explanation:

<h2>Linear equation:</h2>

   An equation of the form ax + by +c = 0, where x and y are two variables and a, b,c are the non-zero real numbers is called a linear equation and the degree of the equation is 1.

       y = 1 - x

x + y - 1 = 0

Where a = 1 ; b=1 and c = -1

So, y = 1 -x is a linear equation.

I need help with my homework, and the question is:
Rasek [7]

Answer:

When the line intercepts the x axis, this means that y will be 0.

therefore the 2 coordinates the line passes through are (2,-5) and (4,0)

given equation of line:

y=mx+b

where m = slope

b = y-intercept.

Let (2,-5) and (4,0) be (x1,y1) and (x2,y2) correspondingly.

slope of line = y1-y2 / x1 - x2

=  \frac{ - 5 - 0}{2 - 4}  \\  =  \frac{ - 5}{ - 2}  \\   = \frac{5}{2}

Now substitute x = 4, y = 0 and m = 5/2 into equation of line to find b.

0 = ( \frac{5}{2} )(4) + b \\ 10 + b = 0 \\ b = 0 - 10 \\  =  - 10

therefore equation of line will be:

y =  \frac{5}{2} x - 10

Below is the table of values of a function. Write the output when the input is n.
trasher [3.6K]

Answer:

when input = n, Output = 4n

Step-by-step explanation:

Output = k(input)

Where,

k = constant

Find k When output = 8 and input = 2

Output = k(input)

8 = k(2)

8 = 2k

k = 8/2

k = 4

Find k When output = 28 and input = 7

Output = k(input)

28 = k(7)

28 = 7k

k =28/7

k = 4

Find output when input = n

Output = k(input)

= 4(n)

= 4n

Output = 4n

when input = n, Output = 4n
