Slope = (10-1)/(1+2) = 9/3 = 3

y = mx + b
1 = 3(-2) +b
1 = -6 + b
b = 7

equation

y = 3x + 7
or
3x - y = -7

answer is 3x − y = −7 (first choice)

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

Rewriting our equation with parts separated

2/3+1+3/8

Solving the fraction parts

2/3+3/8=?

Find the LCD of 2/3 and 3/8 and rewrite to solve with the equivalent fractions.

LCD = 24

16/24+9/24=25/24

Simplifying the fraction part, 25/24,

25/24=1 1/24

Combining the whole and fraction parts

1+1+1/24=2 1/24

The table below shows all of the possible outcomes for rolling two six sided number cubes what is the probability of rolling an

Vanyuwa [196]

Answer:

The probability of rolling an even number first and an odd number second is $\frac{1}{4}$

Solution:

As two cubes are 6 sided, the total number of possibilities are $(6\times6) = 36$

Now in those possibilities the first number will be even and the second number will be odd. If we check the table, such pairs are,

(2,1), (2,3), (2,5), (4,1), (4,3), (4,5), (6,1), (6,3), (6,5)

So, we can see we have total 9 set with the combination of first number even and second number odd. So, the probability of rolling with this combination will be $\bold\frac{9}{36}=\frac{1}{4}\bold$
