Q. How many solutions does the system of equations below have?y=−2x−10y=−2x+74Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze Equations: Analyze the given system of equations.The system of equations is:y=−2x−10y=−2x+74Both equations are in the slope-intercept formy=mx+b, where m is the slope and b is the y-intercept. Compare the slopes of the two lines.
Compare Slopes: Compare the slopes of the two lines.The slope of the first line is −2 and the slope of the second line is also −2. Since the slopes are equal, the lines are either parallel or the same line.
Compare Y-Intercepts: Compare the y-intercepts of the two lines.The y-intercept of the first line is −10 and the y-intercept of the second line is 74. Since the y-intercepts are different, the lines are parallel and do not intersect.
Determine Solutions: Determine the number of solutions.Since the lines are parallel and have different y-intercepts, they will never intersect. Therefore, there are no solutions to the system of equations.
