The slope-intercept form: y = mx + b.

m - slope, b - y-intercept

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (0, 75) → y-intercept (b = 75), and (7, 40).

Substitute the coordimates of the points to the formula of a slope:

$m=\dfrac{40-75}{7-0}=\dfrac{-35}{7}=-5$

<h3>Answer: y = -5x + 75.</h3>

Solve for X<br><br> 4X-(9-3X)=8X-1

Nataliya [291]

4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1 (-8x from each side)

-x - 9 = -1 (+9 to each)

-x = 8 (divide -1 from each side)

x = -8

To play his game, Charles must distribute 350 tokens, when there are 7 players. How many will he have to distribute for 11 playe

Rzqust [24]

First divide 350 with 7

350/7 = 50.

Each player gets 50 tokens.

Now there are 11 players.

Multiply 50 with 11

50 x 11 = 550

550 tokens are distributed for 11 players
