What is the equation in point-slope form of the line that passes through equation in the given points (4,1) and (-2,7)?
Here's how I did it:
Point-slope form is shown here:
As you can see, we need to know the value of the slope and one point value.
To find the slope, we use the formula
So let's plug in the value of the points:
The slope is
Since we have the value of two points, let's put one of them into the equation:
Hope this helps!
