Question

The graph below shows how the height of a bamboo plant is changing over time.

Which equation describes the relationship between x, the number of days, and y, the height of the plant in meters.
pick an answer:
y=0.3x+2
y=0.3x+5
y=3x+2
y=3x+5

Answer 1

Y=0.3x+2
The y-intercept is (0,2). The y-intercept is the “b” in the “y=mx+b” equation
The m is the slope. So the easiest way to salicylate slope on a graph like this is to count. Slope is rise over run (rise/run). The line goes up 1 and over 3.

Answer 2

y=0.3x+2

Explanation:

0.3x+2 because the starting height is 2 meters and the height increases at a constant rate of 0.3 meters a day.
