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
. When knowing the slope of a line and a point it intersects, we can write its equation with that formula. Substitute  ,
,  , and
, and  for real values.
 for real values. 
1) First, find  , or the slope. Use the slope formula
, or the slope. Use the slope formula  and substitute the x and y values of the given points. Then, solve:
 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
. Since  represents the slope, substitute -10 in its place. Since
 represents the slope, substitute -10 in its place. Since  and
 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:
