What are linear equations?
Linear equations are equations that have constant average rates of change, slope or gradient
How to graph and label each cell phone plan?
The cell phone plans are given as:
Cell phone plan 1: y= 7.5x
Cell phone plan 2: y= 5.5x + 10.1
To plot the graph of both plans, we make use of the following domain for both cell phone plans
Domain: x >= 0
Next, we set x = 0, 1, 2, 3, 4 and 5 for both plans
So, we have:
Cell phone plan 1
y= 7.5x
When x = 0, y = 7.5 * 0 = 0
When x = 1, y = 7.5 * 1 = 7.5
When x = 2, y = 7.5 * 2 = 15
When x = 3, y = 7.5 * 3 = 22.5
When x = 4, y = 7.5 * 4 = 30
When x = 5, y = 7.5 * 5 = 37.5
Cell phone plan 2
y= 5.5x + 10.1
When x = 0, y = 5.5*0 + 10.1 = 10.1
When x = 1, y = 5.5 * 1 + 10.1 = 15.6
When x = 2, y = 5.5 * 2 + 10.1 = 21.1
When x = 3, y = 5.5 * 3 + 10.1 = 26.6
When x = 4, y = 5.5 * 4 + 10.1 = 32.1
When x = 5, y = 5.5 * 5 + 10.1= 37.6
Next, we plot both graphs on the domain x >= 0
