8

Front

Which equation represents the graph with a slope of 2 and a y-intercept of 3?

Back

y = 2x + 3

Back

y = mx + b

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the x-intercept of a linear equation?

Back

The point where the line crosses the x-axis (y=0).

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.
