Which equation represents a linear function?
Mila [183]

The equation y - 2 = -5(x - 2) represents a linear function ⇒ 1st answer

Step-by-step explanation:

A linear function is any function that graphs to a straight line

(not a vertical line)

The forms of the linear equation are

  • y = m x + b, where m is the slope of the line which represents the function and b is the y-intercept ⇒ slope-intercept form
  • y-y_{1}=m(x-x_{1}), where m is the slope and (x_{1},y_{1}) is a point lies on the line which represent the function ⇒ slope-point form
  • Ax + By = C, where A, B, and C are constant ⇒ standard form

Linear function means the greatest power x and y in the equation of the function is 1

∵ The equation is y - 2 = -5(x - 2)

∵ The greatest power of x and y is 1

∵ The equation is in the form of y-y_{1}=m(x-x_{1}), where

   m = -5 and the coordinates of the point are (2 , 2)

∴ The equation represents a linear function

The equation y - 2 = -5(x - 2) represents a linear function
