What is the equation of a line that passes through the point (1, 3) and is parallel to a line with a slope of -2? a. y = -2x + 3 b. y = -2x + 5 c. y = 2x + 3 d. y = 2x + 5

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

Parallel lines have the same slope. Therefore m = -2.

We have the equation of a line:

y = -2x + b

Put the coordinates of the point (1, 3) to the equation of a line:

3 = -2(1) + b

3 = -2 + b       add 2 to both sides

5 = b → b = 5

here the number -5 is all of the following except a rational number.

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
