Help please ASAP I don’t really understand it!!

Answer:

y=-2x+1

Step-by-step explanation:

The slope is negative 2 because the way the line is pointing, and the y-intercept is 1.

Answer:

  use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

  m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

  (hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

  m = (75 -25)/(2 -1) = 50 . . . . miles per hour

__

You can identify four (4) regions on this graph in which the slope is constant:

  (0, 1) . . . slope is 25 mph

  (1, 2) . . . slope is 50 mph, as computed above

  (2, 3) . . . slope is 0 (the rider has stopped)

  (3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

Answer:

x = 43

Step-by-step explanation:

lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14

this means that 143 would have to be congruent to 3x + 14

so we can set the equation to 3x + 14 = 143

subtract 14 from both sides: 3x = 129

divide both sides by 3: x = 43

Answer:

$2.19

Step-by-step explanation:

Given that :

Cost of 3 pounds of grape = $6.57

Cost in dollars = y ; number of pounds = x

Cost in dollars α number of pounds

Cost in dollars = k * number of pounds

k = constant of proportionality

$6.57 = k * 3

$6.57 = 3k

Divide both sides by 3

6.57 / 3 = 3k/ 3

2.19 = k

k = $2.19

Answer:

the answer is 56.

Step-by-step explanation:

2 for every 4 = 1 for every two, so 28 multiplied by two.

Answer:

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

[tex] \longrightarrow [/tex] y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

[tex] \longrightarrow [/tex] y² + (6 - 4)y -24

[tex] \longrightarrow [/tex] y² + 6y - 4y - 24

[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)

[tex] \longrightarrow [/tex] (y + 6)(y - 4)

Answer:

( y-4) ( y+6)

Step-by-step explanation:

= y^2 + ( 6 - 4)y - 24

= y^2 + 6y - 4y - 24

= y( y + 6) - 4(y + 6)

= ( y - 4 ) ( y + 6)

Answer:

first solve for x

8x=20

x=2.5

5x=17

x=3.4

then your equations

Madison: y=2.5x

Lucas: y=3.4x

then your ordered pairs

Madison: (4,10)

Lucas:(3,10.2)

then your slope

Madison-2.5

Lucas-3.4
