Answer:
Function 3 is less steep
Explanation:
There are three ways you can figure out the steepness of the slope; draw a graph, plug in a random set of data or use general knowledge.
(1) By observing the graph:
The blue slope = 2x
The red slope = 0.5x
The 2x is much steeper than 0.5x.
(2) By observing the data points (Plugging in the x-value of your choice):
y=0.5x
x: 0, 2, 4, 6, 8, 10
y: 0, 1, 2, 3, 4, 5
y=2x
x: 0, 2, 4, 6, 8, 10
y: 0, 4, 8, 12, 16, 20
The significant difference is visible in the rate of how y inc.
(3) General knowledge:
The bigger the number is for the slope, the steeper the slope is.
The smaller the number is for the slope, the less steep it is.
