Write the slope-intercept form of the equation for the line. y = 2x – 1
y = – 2x – 1
y = 1/2 x-1
y = 1/2 x+1

y = 2x - 1

General Formulas and Concepts:

Pre-Algebra

Algebra I

Slope Formula:

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Find points on the graph.

Point (1, 1)

Point (-1, -3)

Step 2: Find slope m

Step 3: Find y-intercept b

Given: (0, -1) as y-intercept

Step 4: Write linear equation

y = 2x - 1

Step-by-step explanation:

(-1, -3) (1,1)

(1+3)/(1+1) = 4/2= 2

y + 3 = 2(x + 1)

y + 3 = 2x + 2

y = 2x - 1

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
