Q. How many solutions does the system of equations below have?y=−2x−7y=38x+91Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze slopes of equations: Analyze the slopes of both equations.The slope of the first equation y=−2x−7 is −2.The slope of the second equation y=38x+91 is 38.Since the slopes are different, the lines are not parallel.
Determine if lines intersect: Determine if the lines intersect.Because the slopes are different, the lines must intersect at exactly one point.Therefore, there is one solution to the system of equations.
