Final Algebra STAAR Review

If you were to solve this equation with Desmos, what would you do?
3(n - 1) = 2n + 9

• I would type the whole thing in just like it looks:

  3(n - 1) = 2n + 9

• I would type in left side and right side into separate rows, also change n to x

  y = 3(x - 1)

  y = 2x + 9

  Where ever they met on the graph, the first number (x) would be the answer

• I would type in left side and right side into separate rows, also change n to x

  y = 3(x - 1)

  y = 2x + 9

  Where ever they met on the graph, the second number (y) would be the answer

When you graph the exact same equation twice,

• you will have no solution. 
• you will have one solution.
• you will have infinite solutions. 
• you will graph a giraffe.

If I want to find the slope (rate of change), then I should use:

Select all that would work

• rise over run

• run over rise

• y2 - y1 / x2 - x1

• x2 - x1 / y2 - y1

• y1 ~ mx1 + b

  and find the m value
