Which describes the system of equations below? y = –9x − 8 y = –2/5x + 1/2 Choices: (A)inconsistent (B)consistent and dependent (C)consistent and independent

Identify slopes: We have the following system of equations: y = –9x − 8 y = –2/5x + 1/2 Identify whether the slopes of both the equations are the same. In y = –9x − 8, the slope is –9. In y = –2/5x + 1/2, the slope is –2/5. No, the slopes of both the equations are not the same.Determine intersection: Since the slopes are different, the lines are not parallel and will intersect at exactly one point. This means the system of equations has one solution where the two lines intersect. Therefore, the system of equations is consistent and independent.

\newline

y = -\frac{2}{5}x + \frac{1}{2}

\newline

Choices:

\newline

(A)inconsistent

\newline

(B)consistent and dependent

\newline

(C)consistent and independent

Identify slopes: We have the following system of equations: $\newline$ $y = -9x - 8$ $\newline$ $y = -\frac{2}{5}x + \frac{1}{2}$ $\newline$ Identify whether the slopes of both the equations are the same. $\newline$ In $y = -9x - 8$ , the slope is $-9$ . $\newline$ In $y = -\frac{2}{5}x + \frac{1}{2}$ , the slope is $-\frac{2}{5}$ . $\newline$ No, the slopes of both the equations are not the same.
Determine intersection: Since the slopes are different, the lines are not parallel and will intersect at exactly one point. This means the system of equations has one solution where the two lines intersect. Therefore, the system of equations is consistent and independent.
