Answer:

The proper format of x = -1 is a vertical line.

Step - By - Step Explanation:

• The definition of a linear equation is an algebraic expression in which each term has an exponent of one and the graphing of the equation results in a straight line.

• Linear equations are oftentimes written in the form:

  • y = mx + b

• Slope: Or the gradient of a line is a number that describes both the direction and the steepness of the line.

  • The slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between any two distinct points on a line. It is written in the form:
  • m = rise (change in y) ÷ run (change in x) = (y2 - y1) ÷ (x2 - x1)
  • m = slope
  • (x1 , y1) = coordinates of the 1st point
  • (x2 , y2) = coordinates of the 2nd point

• There are three major forms of linear equations:

  • Point - Slope Form
  • Standard Form
  • Slope - Intercept Form

• Point - Slope Form: It emphasizes the slope of the line and a point on the line (that is not the y - intercept). It is written in the form:

  • y - y₁ = m (x - x₁)
  • y = y - coordinate of the 2nd point
  • y₁ = y - coordinate of the 1st point
  • m = slope
  • x = x - coordinate of the 2nd point
  • x₁ = x - coordinate of the 1st point

• Standard Form: Is just another way of writing the equation of the line. It is written in the form:

  • Ax + By = C
  • A = integer
  • x = x - intercept
  • B = integer
  • y = y - Intercept
  • C = integer

• Slope - Intercept Form: Is a way of writing the equation of a line so that the slope of the line and the y - intercept are easily identifiable. It is written in the form:

  • y = mx + b
  • y = y - coordinate
  • m = slope
  • x = x - coordinate
  • b = y - intercept

• The function x = -1 means that for all values of y, the value of x = -1. This is represented by a vertical line at x = -1.

• The slope of the line x = -1 is unknown. The slope doesn't exist because there is no y - value, and the x - value would be 0 and you can't divide by 0.

• Vertical Lines help determine if a relation is a function in math. The equation of a vertical line always takes the form x = k, where k is any number and k is also the x - intercept.
