Q. How many solutions does the system of equations below have?y=−3x+3y=−3x−57Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze Equations: Analyze the given system of equations.We have two equations:1. y=−3x+32. y=−3x−57Both 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.The slope of the first equation is −3, and the slope of the second equation is also −3. Since the slopes are equal, the lines are either parallel or the same line.
Compare Y-Intercepts: Compare the y-intercepts.The y-intercept of the first equation is 3, and the y-intercept of the second equation is −57. Since the y-intercepts are different, the lines are parallel and do not intersect.
Determine Solutions: Determine the number of solutions.Parallel lines never intersect, so there are no points that satisfy both equations simultaneously. Therefore, the system of equations has no solution.
