38. same slope, different y-intercept, no solution.

different slope, one solution.

same slope, same y-intercept, unlimited number of solutions.

39.The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.

40.After simplifying, the first step in solving an equation with a variable on both sides is to get the variable on one side. In other words, we must add to both sides or subtract from both sides one of the quantities that contains the variable.

41.The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

42. Elimination. If necessary, rearrange both equations so that the x-terms are first, followed by the y-terms, the equals sign, and the constant term (in that order). If an equation appears to have not constant term, that means that the constant term is 0.

43. i cant answer dis bc yu i think there is a problem and idk what it is...
