Answer:

The answer to your question is letter C

Step-by-step explanation:

To find the slope and the y-intercept solve the equation of the line for y.

4x + 5y = -9

- Substract -4x in both sides

4x - 4x + 5y = -4x - 9

- Simplify

5y = -4x - 9

- Divide by 5 both sides

5y/5 = -4/5x - 9/5

- Simplify

y = -4/5x - 9/5

- Find the slope

m = -4/5

- Find the y-intercept

b = -9/5

Which number is an integer? 1, 0.5, 3/2

aksik [14]

An integer is any whole number (not fractions) that can be either negative or positive.

1 is the only integer because 0.5 and 3/2 are not whole numbers and are fractions, while 1 is a whole number.
