What is the definition of y-intercept?

• The y-intercept is the point where a line intersects another line.

• The y-intercept is the point where a line crosses the y-axis.

• The y-intercept is the slope of a line.

• The y-intercept is the point where a line crosses the x-axis.

The slope is ​ ​ (a)   , and the y-intercept is ​ (b)   . The graph represents a ​ (c)   relationship.

• negative

• 0

• proportional

• positive

• non-proportional

• 1

• -1

• 2

The slope represents the average number of​ ​ (a)   grows each day. The ​ (b)   represents the ​ (c)   when it is first planted.

• inches a bamboo plant

• y-intercept

• height of the plant

• x-intercept

• number of days
