How do you find an equation of the line containing the given pair of points (-7, -4) and ( -2, -6)?
See a solution process below:
First, we need to determine the slope of the line running through the two points. The slope can be found by using the formula:
Substituting the values from the points in the problem gives:
We can now use the point-slope formula to write and equation for the line. The point-slope formula states:
Substituting the slope we calculated and the values from the first point in the problem gives:
We can also substitute the slope we calculated and the values from the second point in the problem giving:
See the explanation.
First find the slope ,
Either point can be 1 or 2. I'm going by the order listed in the question. Point 1
Insert the points into the equation.
Now use the point slope form for a straight line.
Insert either point as
