graph the lines Slope -1 passing through point (2,2)
The graph of the equation (y = x ) is attached below and this can be determined by using the point-slope form of the line.
Given :
A line with a slope of 1 that passes through the point (2,2).
The following steps can be used in order to sketch the graph a line with a slope of 1 that passes through the point (2,2):
Step 1 - First, determine the equation of the line that passes through the point (2,2) and has a slope of 1
Step 2 - Point-slope form can be used in order to determine the equation of a line.
y-y1 = m(x- x1)
where m is the slope and (x1, y1) is the point on the line.
Step 3 - Substitute the known terms in the above formula.
y-2 = 1(x-2)
Step 4 - Simplify the above equation.
y-2=x-2
x=y
Step 5 - Now, graph the above equation. The graph of the equation
(y = x ) is attached below.

The distance of the segment formed by the two points
is 15. What is the number that goes in the blank?
Explain or show your reasoning.
(-3,-4) (6, _)
The missing coordinate can either be - 16 or 8.
Let the missing coordinate be x.
Now, we know that the distance between (-3, -4) and (6, x) is 15.
Using the distance formula, we get that:
Distance² = (x₂ - x₁)² + (y₂ - y₁)²
Substituting the values in the formula, we get that:
15² = (6 + 3)² + ( x + 4)²
225 = 9² + x² + 16 + 8 x
225 = 81 +x² + 16 + 8 x
225 = x² + 8 x + 97
x² + 8 x - 128 = 0
x² + 16 x - 8 x -128 = 0
x ( x + 16) - 8 ( x + 16) = 0
(x + 16)(x - 8) = 0
x = -16 or x = 8.
Therefore, the missing coordinate can either be - 16 or 8.

Ray BD bisects angle abc. Find the m angle abd m angle cbd and m abc
m∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°;
Bisector BD bisects ∠ABC.
∠ABD= (8x+35)°, ∠CBD= (11x+23)°.
As given, bisector BD bisects the angle ABC so this means, the angle ABC is divided into two halves.
So,
angle ABD= angle CBD.
and ∠ABD= (8x + 35)° (i)
∠CBD= (11x + 23)° (ii)
So,
(8x + 35)° = (11x + 23)°
On solving the above equation, we have
3x= 12
x= 4.
Putting x=4 in (i) we have,
∠ABD= 8(4) + 35
∠ABD= 67°
As ∠ABD = ∠CBD, we have
∠CBD= 67°
Now,
∠ABC= ∠ABD + ∠CBD
∠ABC= 67° + 67°
∠ABC= 134°.
Hence, m∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°.

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.
Let the number student tickets sold = x
Let the number adult tickets sold = y
