Question 1 of 5
Slope-Intercept Equation

A line on the coordinate grid can be defined by a slope-intercept equation: y = mx + b. For a given value of x, the value of y can be determined given the slope (m) and y-intercept (b) of the line. The slope of a line is change in y over change in x, \({\Delta y \over \Delta x}\), and the y-intercept is the y-coordinate where the line crosses the vertical y-axis.

Which of the following is not required to define the slope-intercept equation for a line?

y-intercept

\({\Delta y \over \Delta x}\)

slope

x-intercept
