Answer:

Step-by-step explanation:
The point-slope formula is
. When knowing the slope of a line and a point it intersects, we can write its equation with that formula. Substitute
,
, and
for real values.
1) First, find
, or the slope. Use the slope formula
and substitute the x and y values of the given points. Then, solve:

Therefore, the slope of the line is -10.
2) Now, substitute the needed real values into the point-slope formula,
. Since
represents the slope, substitute -10 in its place. Since
and
represent the x and y values of a point the line crosses, choose any of the points given and substitute its values into the formula. (Either one is fine, they both equal the same thing. I chose (2,3).) This will give the following answer and equation:

Coordinates of point C: (1,-1)
Step-by-step explanation:
In this problem, A, B and C are collinear, and B is between A and C.
The ratio AB : BC is 3 : 1.
This means that we can write the following two equations:

where:
are the coordinates of point A
are the coordinates of point B
are the coordinates of point C
Solving the equation for
,

Solving the equation for
,

So, the coordinates of point C are

Answer:
x = 17
Step-by-step explanation:
The sum of all angle measures in any triangle is 180 degrees.
- Thus, 23 + 5x - 18 + 90 = 180.
Step 1: Simplify both sides of the equation.
Step 2: Subtract 95 from both sides.
Step 3: Divide both sides by 5.
Step 4: Check if solution is correct.
Thus, x = 17.
