What does the equation x = 1 represent on a graph?

Back

A vertical line that crosses the x-axis at x = 1.

Front

What is the definition of the y-intercept in a linear equation?

Back

The y-coordinate of the point where the line crosses the y-axis, which occurs when x = 0.

Front

Write the equation of a line with a slope of 3 and a y-intercept of 2.

Back

Back

Front

What does the term 'rise' refer to in the context of slope?

Back

The vertical change between two points on a line.

Front

What does the term 'run' refer to in the context of slope?

Back

The horizontal change between two points on a line.

Front

How do you identify the slope from the equation of a line in slope-intercept form (y = mx + b)?

Back

The slope is the coefficient of x, represented by m.
