For this case we have that by definition, the point-slope equation of a line is given by:
Where:
m: It's the slope
It is a point through which the line passes
According to the statement data we have:
Substituting we have:
By law of signs of multiplication we have to:
Answer:
The requested equation is: 
It is a constant. hope this helps
so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
Answer:
= -3
Step-by-step explanation:
Find 2 points
(-2, 4) and (1,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-5-4)/(1 - -2)
= -9/(1+2)
= -9/3
= -3
