The description below represents Function A and the table represents Function B:
ICE Princess25 [194]
The expression in A is equal to: 
                      y = 8 + 3x
It can be observed that the equation is in the slope-intercept form which is equal to,
                     y = mx + b
where m is slope and b is intercept.

The slope and intercept therefore of this equation of the line are equal to 3 and 8, respectively.

For Part B:
 The slope of the line can be calculated through the equation,
                           m = (y₂ - y₁) / (x₂ - x₁)
Substituting,
                           m = (5 - 2)/ (0 - -1) = 1.5

The intercept, b, is the value of y when x = 0. From the tabulation, y = 5 when x = 0. Thus, the intercept is equal to 5.

Comparing the slopes and intercepts of the equations, we can say that the slope of the second is only half that of the first and the intercept of the second is 3 less than that of the first equation.

ivanzaharov [21]

Answer:

1/45 ≈ 0.022

Step-by-step explanation:

There are originally 10 juice boxes in the cooler, 2 of which are grape.

The probability that the first juice box is grape is 2/10.

The probability that the second juice box is grape is 1/9.

The probability of both is (2/10) (1/9) = 1/45 ≈ 0.022.
