some of the water features at sapphire island are periodically treated with a chemical that prevents algae growth. the directions for the chemical say to add 16 fluid ounces per 10,000 gallons of water. how do i write a linear equation in two variables that model the situation

    The linear equation will have the form y = mx + b where x = amount of 10K gallons of water y = total amount of chemical mixture m = the slope of the line b = amount of fluid ounces added

    The only thing you need to input is m and b

    I agree it's not obvious, but let's do it this way. Let's focus only on the essential statement of the problem.

    "Add 16 fluid ounces of chemical for every 10,000 gallons of water"

    You can take that statement and directly convert it to a mathematical expression.

    You can also re-write it this way: "For every 10,000 gallons of water add 16 fluid ounces of chemical."

    I'm just giving you ideas for how you can approach this.

    Try to think about it a bit more and see if you can come up with the correct expression. Just try to focus on creating an expression for mx + b for right now.

    y and x will always be in a linear equation. It's m and b that get replaced with numbers. 10,000 should definitely be in the equation as well.

    y = 10,000x + 16

    Really, it depends on how the x is defined.

    If you define x as amount of gallons of water (in tens of thousands), then you can write it as y = x + 16

    You already graphed it, but still don't know the slope or the y-intercept? How did you manage to graph it without that?

    i have no clue it just told me to graph it and then it toldme to find the slope and y intercept.
