Rodney's errors on each of the graphs given can be explained as in the explanation below.
<h3>Linear graphs of slope-intercept form equations</h3>
Rodney's error on each of the given linear graphs are as follows;
For y= 30x +10;
- The slope of the graph is 30 and it's intercept is; 10. Hence, the graph should intersect/touch the y-axis at (0,10)
For y= (-1/2)x +5;
- The slope of the given function is; -1/2 and hence, the graph should be a decreasing linear graph.
For y= x -2;
- The slope and intercept of the given function are 1 and -2 respectively. On this note, the graphed line should intersect the y-axis at point (0, -2) and the graph should be an increasing linear graph.

Answer:
30 different types of tacos can Rico make.
Step-by-step explanation:
Given - The list below shows the different taco shells, fillings, and toppings sold at Rico's Taco Bar.
Taco Shells Fillings Toppings
Soft Chicken Cheese
Hard Beef Lettuce
Bean Sour Cream
Onions
Salsa
To find - How many different types of tacos can Rico make using one taco shell, one filling, and one topping?
Proof -
Given that,
There are 2 different types of Taco shells, 3 different type of fillings and 5 different types of toppings.
So, by the fundamental principal of counting,
Total types of tacos Rico made = 2 × 3 ×5 = 30
10 + 3(2) - 1
10 + 6 - 1
16 - 1
