Solving linear simultaneous equations graphically

Simultaneous equations always have solutions.

Simultaneous equations can only be solved using graphs.

Simultaneous equations do not always have solutions.

Simultaneous equations never have solutions.

Which of the following statements is true?

Which of the following equations do not have solutions when solved simultaneously?

Which of the following equations have a solution where the x coordinate is negative?

Which of the following equations have a solution where both the coordinates are negative?

Which of the following equations have a solution where both the coordinates are positive?

Fill in the gaps: We can use ____ to solve simultaneous equations.

What are the coordinates of the points of intersection for y = x + 5 and y = -2x - 1?

Use a graph to solve y = x + 5 and y = -2x - 1 simultaneously.

Create equations for the following statements: "I'm thinking of 2 numbers that have a sum of 3", "I'm thinking of 2 numbers. I triple the first number and add the second to get -1".

Find the values of x and y that are true for both of the following statements: "I'm thinking of 2 numbers that have a sum of 3", "I'm thinking of 2 numbers. I triple the first number and add the second to get -1".
