Question

1. -5 represents which type(s) of number? select all the correct answers.

a integer
b irrational number
c rational number
d real number
e whole number

1. what is the solution to the system of equations?

a (0, 1)
b (1, 2)
c (4, 5)
d (5, 4)

Explanation:

For Question 5:

• Integers include all positive/negative whole numbers and 0, so -5 is an integer.
• Rational numbers are numbers that can be written as $\frac{a}{b}$ where $a,b$ are integers ($b

eq0$); $-5=\frac{-5}{1}$, so it is rational.

• Real numbers include all rational and irrational numbers, so -5 is a real number.
• Whole numbers are non-negative integers (0,1,2,...), so -5 is not a whole number. Irrational numbers cannot be written as a fraction of integers, so -5 is not irrational.

Step1: Identify intersection point

The solution to a system of linear equations graphed is the point where the two lines cross. On the grid, the lines intersect at the coordinate $(5,4)$.
