An equation is shown below: 5x - y = 8 Part A: Explain how you will show all of the solutions that satisfy this equation. (4 points) Part B: Determine three different solutions for this equation. (4 points) Part C: Write an equation that can be paired with the given equation in order to form a system of equations that is inconsistent.

    I'd graph the line so show all the solutions... the line is made up of all the points that follow the rule

    so to get 3 different solutions substitute x -0, x = 1 and x = 2 and find the corresponding y values for an inconsistent solution, you could use a multiply of the line or a parallel line

    ok... so if you rewrite the equation you get y = 5x - 8 this is a line you can graph on the number plane let x = 0 y = 5 *0 - 8 so y = -8 the point (0, -8) is on the line x = 1 y = 5*1 - 8 so y = -3 the point (1, -3) is on the line you can do the same for x = 2 to find a point so for the inconsistent line you might choose a line that is parallel or a line that is a multiple 5x - y = 8 multiply every term by 2 what do you get.... then go and graph it
