Write the equation of line whose x-intercept is 3 and y-intercept is -2

Question

 I need to find an equation 

Answer 1

x intercept 3 : (3,0)

y intercept -2 : (0.-2)

 

slope of line = -2-0  / 0 -3 = -2/-3 = 2/3

 

slope intercept form  is y = mx+b   where m is slope and b is y intercept

 

                                 

y = (2/3) x  -2

Answer 2

You have 2 points:

 

(3,0)

(0,-2)

 

m = (-2 - 0)/(0 - 3) = 2/3

 

y = mx + b = (2/3)x + b

 

b = -2  [given]

 

y = (2/3)x - 2
