Answer:

1) (the red) y= 3x +2

2) (the green) y= -1x + 4

Step-by-step explanation:

Slope intercept form: y = mx + b

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

you can find the slope by using the formula \frac{rise}{run}, where you use two points on the line and find the space between the two.

Pic 1 or has line that is orange

y=3x+2

Pic 2 or has line that is green

y=-1x+4

Slope intercept form is y=mx+b.

m=slope

b=y-intercept

For pic 1, the point which is intercepted at the y-axis is 2, so the y-intercept is 2.

To find the slope, we take two points, I'm using (-1,-1) and (-2,-4) and divide y2-y1 and x2-x1.

-4-(-1)  /  -2-(-1)

= -3/-1 = 3

b= 2

m= 3

y=3x+2

For pic 2, the point that is intercepted at the y-axis is (0,4), so the y-intercept is 4.

To find the slope, we take the two points (-2,6) and (-1,5) and divide.

5-6 / -1-(-2)

= -1/1 = -1

b= 4

m= -1

y=-1x+4

On Monday, during a one day sale, the price of a suit was decreased by 20%. On Tuesday, the price of the suit was changed back t
nignag [31]

Answer:

25%

Step-by-step explanation:

If we consider the original price of the piece of suit is x.

Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.

Therefore, the new price of the suit on Monday is x( 1 - \frac{20}{100}) = 0.8x.

Now, the price of the suit on Tuesday was changed back to the original price i.e. x.

Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.

So, the percentage change in price of the suit on Tuesday is \frac{0.2x}{0.8x} \times 100 = 25%. (Answer)

Seth’s father is thinking of buying his son a six-month movie pass for $40. With the pass, matinees cost $1.00. If matinees are
Ymorist [56]

Answer:

In order for it to benefit his father to buy the pass Seth have to attend the movies for 11 times.

Step-by-step explanation:

Given:

Cost of movie pass = $40

Cost per matinees with pass = $1.00

Cost per matinees without pass = $3.50

To Find:

Number of times must Seth attend in order for it to benefit his father to buy the pass = ?

Solution:

Let x be the number of times he wants to visit

To profit his father

The number of visits without pass =  the number of visits with passin the cost  of $3.50

Then, without pass if he visits for x times then the cost will be  = 3.50x

Also with pass, the number of times he can visit the pass  =  \frac{40}{3.50}

then

\frac{350 x}{3.50} = \frac{40}{3.50}

3.50x = 40

x = \frac{40}{3.50}

x =  11.42

x = 11 (approx)

Slope is 3,and (2,5) is on the line.
bazaltina [42]

Standard form of line:

Ax + By = C

where A, B, and C are integers, and A is positive

slope-point form of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line. Replacing with m = 3 and point (2, 5):

y - 5 = 3(x - 2)

y - 5 = 3x - 3(2) distributing

y - 5 = 3x - 6

y - 5 - y = 3x - 6 - y subtracting y at both sides

- 5 = 3x - 6 - y

- 5 + 6 = 3x - 6 - y + 6 adding 6 at both sides

1 = 3x - y which has the standard form
