Slope equals 2 and the line goes through the point (-1, 3)

astra-53 [7]

Answer:

Well the slope seems rather easy to calculate because you already typed it and it is 2.

First we must solve this equation:

b = y - m*x and we input values into the equation:

b = (3) - (2 * -1)

b = 5

Then, we enter the value of "b" and the slope into this equation:

y = mx +b

y = 2x + 5

A box of Jell-O costs $0.50, and makes 2 cups. How much would it cost to fill a swimming pool 4 feet deep, 8 feet wide, and 12 f

garik1379 [7]

Answer:

$11,520

Step-by-step explanation:

4 * 8 * 12 = 384 cu ft.

384 * 7.5 = 2880 gallons

There are 16 cups in a gallon

2880 * 16 = 46,080 cups

46,080/2 * .50 = $11,520

Which of the following equations has a slope of -2 and passes through the point (2,3)?

ryzh [129]

Option C (Same as Option D)

<h2>Explanation:</h2>

Option C and D are the same, so I'll assume you made a mistake when writing this question. However, let's figure out which of the following equations has a slope of -2 and passes through the point (2,3):

A. y = -2x + 6

B. y - 3 = -2(x + 2)

C. y = -2x + 7

<em />

<em>All these equations have a slope of -2.</em>

FROM OPTION A:

$Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+6 \\ \\ 3=-4+6 \\ \\ 3=2 \ False!$

Since $3\neq 2$ then the line doesn't pass through the point (2, 3)

FROM OPTION B:

$Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3-3=-2((2)+2) \\ \\ 0=-2(4) \\ \\ 0=-8 \ False!$

Since $0\neq -8$ then the line doesn't pass through the point (2, 3)

FROM OPTION C:

$Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+7 \\ \\ 3=-4+7 \\ \\ 3=3 \ True!$
