Point-slope form is y-y_1=m(x-x_1).
Example Solution: y-1=-3/2(x-3)
Equations in point-slope form follow a specific format.
y- y_1= m(x- x_1)
In this form, m is the slope of the line and ( x_1, y_1) is a point on the line. Let's choose two points from the given table.
Substitute ( 3,1) & ( 7,-5)
Subtract terms
Put minus sign in front of fraction
a/b=.a /2./.b /2.
Calculate quotient
Now that we know the slope of the line is - 32, we can write the equation of the line in point-slope form. We can use either of the given points as (x_1,y_1) in our equation. Let's use ( 3, 1).
Please note that any point on the line can be used to form a point-slope equation. Therefore, our equation is only one of infinitely many possible equations!
