Question

Write a equation in standard form that represents the points (1, -4) and (3,-5) Answer for

Answer 1

Answer:

Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.

9x+3y = 36

3y= - 9x + 36

y = -3x + 12

The slope, m = -3

------------------

The slope of lines parallel is the same.

The slope of lines perpendicular is the negative inverse, m = +1/3

----------------

Use y = mx + b and the point (1,2) to find b.

2 = (1/3)*1 + b

b = 5/3

The equation is y = (1/3)x + 5/3 (slope-intercept form)

x - 3y = -5 (standard form)

Answer 2

Answer:

he explanation is shown below:

1. You must keep on mind the information given in the exercise:

- She bough 3 pounds of coffee.

- She bought 2 pounds of chocolate.

- She spent a total of $24.

2. Therefore, you can call the price per pound of coffee  and the price per pound of chocolate .

3. When you multiply 3 pounds by the price per pound of coffee, you obtain the amount of money she spent for 3 pounds. When you multiply 2 pounds by the price per pound of chocolate, you obtain the amount of money she spent for 2 pounds. If you add both amounts, you obtain the total spent, which was $24.

4. Therefore, you can express this as following:
