Isla wants to solve the equation 2.5x – 1.75 = 5(7 – 0.5x).

She uses a graphing program to graph the equations y = 2.5x – 1.75 and y = 5(7 – 0.5x).

Use the graph to find the solution of 2.5x – 1.75 = 5(7 – 0.5x).

I would set the first step as ‘Plot the y-intercept (0, -6) as that is immediately the first point that you know is on the line.

Then, the second step would be ‘From the y-intercept, rise up 2 and run to the right 5 to plot a second point’, as this includes the point made in the first step and then allows us to have a second point.

The last step would then be ‘Connect the two points’.

I hope this helps!
