Question

6. Babys length in inches 24 22 21 20 12 16 8 End of gowth period From the given graph, • What is the y-intercept • the behavior of the graph • the slope of the graph

Answer 1

The y intercept = 20

It is a linear graph

slope = 1/4

Explanation:

a) The y intercept is the point the line touches the y-axis (vertical line that represent the babies length in inches). The line touches that line at 20

The y intercept = 20

b) The behaviour:

It is a linear graph (a line graph). And the graph is positive because it increases. This we know because the line is pointing upward.

c) slope = the change in babies length in inches/end of growth period

we pick any two points. (the horizontal, vertical) = (x, y)

using (8, 22) and (4, 21)

slope = (22 - 21)/(8 - 4)

slope = 1/4
