Answer:
These are Vertical angles, adjacent angles are next to each other and make up a whole angle, while vertical angles are across and equal the same thing.
X = 81 because 84 and (x + 3) are the same so 84 minus 3 is 81
Hope that helps
Answer: The slope of the line is 
Step-by-step explanation:
The slope of a line can be calculated with the following formula:

Then, given the points
and
, you can identify that:

Knowing these values you can substitute them into the formula for calculate the slope:

Finally, evaluating, you get that the slope of that line is:

The correct answer is the first option.
If you want to use elimination, you can sum the two equations for example, so that the x's simplify:



Plug this value for y in one of the equations to derive the value of x:

So, the solution is 
Answer: well 56 is the answer
Step-by-step explanation:
Answer:
A line includes the points (4, 8) and (3, 5) whose equation in slope-intercept form will be :

Step-by-step explanation:
The point slope form: 

where : m = Slope of the line

A line includes the points (4, 8) and (3, 5).The equation of the line will be:




(y=mx+c), where c is intercept at y axis.
The above equation represents slope-intercept form of the line.
