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".
