Question 592942: Hello,
I am stuck on how to get further on this problem.
Find an equation of the line containing the given pair of points.
(-5,-9) and (-1,-3)
x,m= y2-y1 over
x2-x1
I would really like to see step by step

First let's find the slope of the line through the points

and

Note:

is the first point

. So this means that and .
Also,

is the second point

. So this means that and .

Start with the slope formula.

Plug in , , , and

Subtract from to get

Subtract from to get

Reduce

So the slope of the line that goes through the points

and

is

Now let's use the point slope formula:

Start with the point slope formula

Plug in , , and

Rewrite as

Rewrite as

Distribute

Multiply

Subtract 9 from both sides.

Combine like terms. note: If you need help with fractions, check out this solver.

So the equation that goes through the points

and

is
