Front

What is the graphical representation of the equation y = 2/3x - 3?

Back

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

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

A negative slope indicates that the line descends from left to right.

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
