Answer:
7, 13 3,7 17,3 13,2
Step-by-step explanation:
The slope of parallel lines is equal and the slope of perpendicular lines is a negative multiplicative inverse of each other.
<h3>What is the standard equation of a line?</h3>
The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y-intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
A square is a polygon with four sides, the opposite sides are parallel and all the sides are equal, all the angles have an equal measure of 90 degrees.
Two lines are parallel to each other when they are at a fixed distance always and never intersect with each other.
The slope of the lines parallel to each other is equal.
Two lines are said to be perpendicular when they intersect at 90 degrees.
The slope of two perpendicular lines has a product of -1.

Part A: Let x and y be the number of persons attending the two-day conference and y be the number of vouchers released. The equation that would best express the given is,
y = 4x
Part B: The number of people attending the conference is determined by dividing the given number of vouchers by 4. The answer is 956.
Answer:
86°
Step-by-step explanation:
The total of all of the angles needs to add up to 180 degrees.
45 + 49 = 94
180 - 94 = 86 degrees
