What is the significance of a positive slope in a linear graph?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward slant of the line.

What does a negative slope indicate about a linear graph?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward slant of the line.

Back

The graph is a straight line with a slope of 2 and a y-intercept of 3.
