Definition:
A line is a one-dimensional figure, characterized by its length but no width (thickness). A line is made of a set of points which is extended in opposite directions infinitely.
A line is determined by two points in a two-dimensional plane such as the x-y plane.
The graph of a function can be represented by a line because all points on the line provide a solution to the function. Such functions are usually linear functions.

I need help pls !!!!!
Answer:
132
Step-by-step explanation:
That is an 180 degree angle so just do:
180-42=a
a=132
Answer:
138 degrees.
Step-by-step explanation:
A straight line is equal to 180 degrees. 42 is some, so you would subtract 180 and 42. That is 138 degrees. (When two or more angles add up to 180 it's called supplementary angle) Hope this helps

what is the standard form for the equation y=-5x+8
Answer
5x+y=8
Step-by-step explanation:
[tex]y + 5x = 8[/tex] is a standard form of equation.
What is standard form?
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. If the equation is given in this form, finding both points of intersection (x and y) is quite easy. This form is also very useful for solving systems of two linear equations.
By some examples,we can understand the concept more easily.
Example -1,
[tex]2x + 3y = 2[/tex] is a standard form of equation.
Example -2,
[tex]5x + 7y = 2[/tex] is a standard form of equation.
Example -3,
[tex]5x = y - 5[/tex] is not a standard form of equation.
Given equation is [tex]y = - 5x + 8....(1)[/tex]
We want to find standard form for the given equation.
Now,
[tex]y = - 5x + 8[/tex]
We are separating variable and constant part.
[tex]y + 5x = 8[/tex]
According to rule,it is a standard form of equation.

What are the measures of the angles in the triangle? (6x + 10) (x + 17) (4x - 34)
I'm not quite sure these are right. You might wanna check with a classmate or something first.
Step-by-step explanation:
(6x + 10) + (x + 17) + (4x - 34) = 180
11x - 7 = 180
11x = 173
x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)
(6x + 10)
6 (15.73) + 10
94.38 + 10
104.38
(x + 17)
(15.73) + 17
32.73
(4x - 34)
4(15.73) - 34
62.92 - 34

Mr. Morales purchases 6 boxes of pencils, 12 boxes of pens, and 4 cases of notebook paper for his classroom. Each box of pencils costs $4.10, each box of pens costs $6.50, and each case of notebook paper costs $105. What is the total cost in dollars of his classroom supplies?
Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
