Why is it recommended to use a ruler when graphing equations?

• To measure the graph accurately

• To make the graph look neat

• To draw straight lines

• All of the above

What is the correct way to plot the equation y = 5/3x + 8?

• Start at 5 on the x-axis, then move up 8

• Start at 3 on the x-axis, then move right 5

• Start at 8 on the y-axis, then move down 5 and left 3

• Start at 8 on the y-axis, then move right 5 and up 3

What should you do if the graphing space is insufficient for plotting a line?

• Stop plotting

• Plot in the opposite direction

• Only plot the intercepts

• Redraw the entire graph

How can you ensure your graphed lines are accurate?

• By using a ruler

• By guessing the slope

• By estimating the points

• By drawing freehand

What does the intersection point of two lines represent in a system of equations?

• The starting point of the graph

• A random point

• The solution to the system

• A mistake in graphing

What is the solution set of a system of equations?

• The set of all possible x-values

• The highest point on the graph

• The set of all possible y-values

• The point(s) true for both equations

What does it mean if two lines in a graph do not intersect?

• The lines are incorrectly drawn

• The system has no solution

• The system has infinitely many solutions

• The system has one solution

What indicates that a system of equations has infinitely many solutions?

• The lines intersect at a single point

• The lines are parallel

• The lines coincide

• The lines form a right angle
