Which describes the system of equations below? y = x − 2 y = 2/5x − 3/7 Choices: (A)consistent and independent (B)consistent and dependent (C)inconsistent

Analyze Equations: To determine the type of system, we need to analyze the slopes and y-intercepts of the two equations. The first equation is y = x − 2, which is in slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. Here, the slope m1 is 1 and the y-intercept b1 is -2.Identify Slopes and Intercepts: The second equation is y = 2/5x − 3/7. It is also in slope-intercept form y = mx + b. Here, the slope m2 is 2/5 and the y-intercept b2 is -3/7.Determine Consistency: Since the slopes m1 and m2 are different (1 ≠ 2/5), the lines are not parallel and will intersect at exactly one point. This means the system is consistent because there is at least one solution.Check for Independence: Because the lines intersect at exactly one point, they are not the same line, and therefore the system is independent (it does not have infinitely many solutions).

Analyze Equations: To determine the type of system, we need to analyze the slopes and y-intercepts of the two equations. $\newline$ The first equation is $y = x - 2$ , which is in slope-intercept form $y = mx + b$ , where $m$ is the slope and $b$ is the y-intercept. Here, the slope $m_1$ is $1$ and the y-intercept $b_1$ is $-2$ .
Identify Slopes and Intercepts: The second equation is $y = \frac{2}{5}x − \frac{3}{7}$ . It is also in slope-intercept form $y = mx + b$ . Here, the slope $m_2$ is $\frac{2}{5}$ and the y-intercept $b_2$ is $-\frac{3}{7}$ .
Determine Consistency: Since the slopes $m_1$ and $m_2$ are different ( $1 \neq \frac{2}{5}$ ), the lines are not parallel and will intersect at exactly one point. This means the system is consistent because there is at least one solution.
Check for Independence: Because the lines intersect at exactly one point, they are not the same line, and therefore the system is independent (it does not have infinitely many solutions).
