Answer:

Point Slope: (y + 1) = 2x

Slope Intercept: y = 2x - 1

Step-by-step explanation:

I'll do it in two forms.

Slope = (3 + 1) / (2 - 0) = 2

Point - Slope: (y + 1) = 2x

Slope Intercept: y = 2x + b

-1 = b

y = 2x - 1

snow_tiger [21]

Answer: The price of Zoe's dinner before sales tax and tips is $13.96.

Step-by-step explanation:

Since we have given that

Amount Zoe paid after sales tax and tip = $18.60

Let the price before tax be 'x'.

Rate of sales tax = 11%

So, it becomes,

\frac{11}{100}\times x\\\\=0.11x

So, Amount after tax, our equation, becomes,

x+0.11x=\$18.60\\\\1.11x=\$18.60\\\\x=\frac{18.60}{1.11}\\\\x=\$16.75

Now, let the amount before tips be 'y'.

Rate of tips = 20%

So, it becomes,

\frac{20}{100}\times y\\\\=0.2y

So, After tips it becomes,

y+0.2y=\$16.75\\\\1.2y=\$16.75\\\\y=\frac{16.75}{1.2}\\\\y=\$13.96

Hence, The price of Zoe's dinner before sales tax and tips is $13.96.
