Desmos Standard Form Equations

Multiple Choice

$$5y-3=2\left(16-y\right)$$

Solve the following equation.

(If you are using the desmos calculator, first change the variable, you can't use y so replace all the y with another letter.)

5x - 3 = 2(16-x)

Multiple Choice

A family bought 2 hamburgers and 4 salads at the fair. The total was $32. Use 𝑥 for the price of a hamburger. Use 𝑦 for the price of a salad.

What will be the equation in standard form for this scenario?

• 2x - 4y = 32

• 2x + 4y = 32

• 2x = 4y + 32

• 4y = 2x + 32

Multiple Choice

2x + 4y = 32

Solve for y.

• $$y\ =\ -2x\ +\ 32$$

• $$y=-\frac{1}{2}x+32$$

• $$y=-\frac{1}{2}x+8$$

Multiple Choice

Vihaan sold 4 bracelets at the fair. To make the bracelets, he bought 8 packs of beads. Vihaan made $32 in total.

Use x for the price of a bracelet.

Use y for the cost of a pack of beads.

Which equation in standard form represents this scenario?

• 4x - 8y = 32

• 4x + 8y = 32

• 4x = 8y + 32

• 8y = 4x + 32

Multiple Choice

4x - 8y = 32

Solve for y.

• $$y\ =\ -2x\ +\ 32$$

• $$y=\frac{1}{2}x-32$$

• $$y=\frac{1}{2}x-4$$
