The equation of the line is y =   x +

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope is m = , where

∵ A line passes through points (2, -1) and (-3, 3)

∴ x1 = 2 ad y1 = -1

∴ x2 = -3 and y2 = 3

→ Use the rule of the slope above to find the slope of the line

∵ m = = =

∴ m =

→ Substitute the value of m in the form of the equation above

∴ y =  x + b

→ To find b substitute x and y in the equation by the coordinates of one  

   point of the given points

∵ x = 2 and y = -1

∴ -1 = (2) + b

∴ -1 = + b

→ Add t both sides

∵ -1 + = b

∴ = b

→ Substitute the value of b in the equation

∴ y = x +

∴ The equation of the line is y =   x +
