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.
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

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

therefore equation of line will be:

Step-by-step explanation:
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
