An oceanographer is studying the growth of giant kelp. They select one giant kelp plant and record its height each day. They they draw a graph where the x-axis represents Time (days) and the y-axis represents the Height (cm). They write the linear equation y=25x + 10 to show the height (y) of the giant kelp plant after (x) days. What does the slope represent in this situation?
What is the average growth rate of the giant kelp, in centimeters per day.
__ represents rise; ___ blank represents run
what is y-axis and x-axis?
Name a possible ordered pair that would make this linear equation true: y= 0.5x + 10
What is *multiple options* as long as the value of y is 10 more than half the value of x
What is the y-intercept of a line that passes through the points (2,7) and (6,1)?
What is 10?
A line that goes downwards from right to left?
What is positive?
Estela is making honey corn bread. She draws a graph that shows the relationship between cups of corn meal (y) and tablespoons of honey (x). How could she show that slope of the line is constant?
**Many answers accepted** along the lines of "mark any two points on the line, use formula or slope triangles to show that the slope is constant/never changing"
What would the slope be of a straight, vertical line?
What is undefined?
