Write the slope-intercept form of the equation of the line through the given point with the given slope.

Marta_Voda [28]

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

Answer: $\textsf{y = x + 2}$

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

Given: $\textsf{Slope = 1, Goes through (-1, 1)}$

Find: $\textsf{Determine the slope-intercept form of the equation}$

Solution: In order to determine the equation we need to first use the point-slope form which uses a slope and a point which can then be simplified and solve for y to get the slope-intercept form.

<u>Plug in the values</u>

$\textsf{y - y}_2\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - 1 = 1(x - (-1))}$

<u>Simplify and solve for y</u>

$\textsf{y - 1 = 1(x + 1)}$

$\textsf{y - 1 + 1 = x + 1 + 1}$

$\textsf{y = x + 2}$

Therefore, the simplified equation in slope-intercept form would be y = x + 2

Type the correct answer in each box. Alan, Bill, and Calvin are playing a game with collectible cards. At the moment, Alan has 1

steposvetlana [31]

Let A be the number of cards Alan has

B be the number of cards Bill has

C be the number of cards Calvin has

Alan had 11 less than 2 1/2 times the number of cards bill has.

is 2.5

Alan is 2.5 of bill has minus 11

A=2.5B -11

Calvin has 1 more than 1 1/2 times the number of cards bill has.

is 1.5

Calvin is 1.5 of bill has plus 1

C=1.5B + 1

Alan and Calvin have the same number of cards

So A=C

WE plug in A and C equations and solve for B

2.5B -11 = 1.5B + 1 (subtract 1.5B on both sides)

1B -11 = 1 (Add 11 on both sides)

B = 12

If Alan and Calvin have the same number of cards, the number bill has is 12

The number of cards Alan and Calvin each have is 19

Total cards = 12 + 19 + 19 = 50

If Alan, bill, and Calvin have all the cards in the deck then the deck has 50 cards
