How do you solve #y-y_1=m(x-x_1)# for m?
This equation is the point slope form for a straight line.
The point slope equation is used to determine the equation for a straight line, given the slope
Plug in given values.
Distribute the 5.
Add 2 to both sides of the equation.
In order to find the slope of a line, using two points on the line, you use the equation
To find the equation of this line using the equation
Plug in the slope and the x and y values for one of the two points. I will use the point
I get the same answer if I use the other point,
So the equation of this line is
