If a line crosses the y-axis at (0, 1) and has a slope of 45, what is the equation of the line?

tamaranim1 [39]

The general equation of a line is expressed as:

y = mx + b

where m is the slope and b is the y-intercept.

We are given the slope of the line and its y-intercept (m = 4/5, b = 1).

y = (4/5)x + 1

5(y - (4/5)x = 1)

5y - 4x = 5

The answer should be option D.

The mean cost for each item in his bag was $3.05. He bought a total of 8 items, and the prices of 7 of those items are listed be

Anna007 [38]

You know the mean cost is calculated from ...

... (mean cost) = (total cost)/(number of items)

You are given the mean cost and the number of items, so you can find the total cost for the 8 items as ...

... (mean cost)×(number of items) = (total cost)

... 8 × $3.05 = (total cost) = $24.40

You are given the costs of 7 of the items so ...

... (total cost) = (8th item cost) + (total cost of 7 items)

Then we can find the (8th item cost) as ...

... (8th item cost) = (total cost) - (total cost of 7 items)

Adding up the given cost of the 7 items, we get ...

... (total cost of 7 items) = $20.57

... (8th item cost) = $24.40 -20.57 = $3.83

The price of the 8th item in the bag was $3.83.

Kolby decided he wanted to go to the amusement park. The amusement park charges $8.00 for entry and $1.40 for each ride.

dimulka [17.4K]

Answer:

He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.

A. $8.00 + $1.40 * r

If his parents gave him $26.00, then that is the most Kolby can spend.

$8 + $1.40 * r = $26

Subtracting 8 from both sides:

$1.40 * r = $18

Dividing both sides by 1.40:

r = 12.86

B. Since you can't ride part of a ride, Kolby can only ride 12 rides.

Passes through the points (−4, 2) and (12, 6)?

svlad2 [7]

<u>I'll assume you need to find the equation of the line that passes through those points.</u>

Answer:

$\displaystyle y-2=\frac{1}{4}(x+4)$

Step-by-step explanation:

<u>Equation of a Line:</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given points are (-4,2) and (12,6), thus:

$\displaystyle y-2=\frac{6-2}{12+4}(x+4)$

Operating:

$\displaystyle y-2=\frac{4}{16}(x+4)$

Simplifying, the equation in point-slope form is:

$\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}$
