Question

Write the equation of the line in

point-slope form that goes through
the points (0, 3) and (1, 1).

Answer 1

y - 3= 2(x - 0)

Explanation:

hello :

note 1 :

the point-slope formula is :

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

note 2 :

the slope is : m = (y_2 - y_1)/(x_2 -x_1) when given two points :

A(x_1 , y_1 ) and B(x_2 , y_2 )

in this exercice : x_1 =0 y_1 =3 x_2 =1 y_2 =1

calculate now m = (1 - 3)/(1 -0) =-2

an equation in point-slope form is : y - y_1 = m(x - x_1)

y - 3= 2(x - 0)
