The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14
Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
Solution: Alyssa is incorrect.
In fact
.
If we cross-multiply the above equation, we have:


Therefore, they are equal.
Also, if we reduce the given fractions, we have:

And

Since both the fractions reduced to
, therefore fractions are equivalent.
Answer:
10
Step-by-step explanation:
Take 4 times 2.5 since 25 / 10 = 2.5
4 x 2.5 = 10
Answer:
Step-by-step explanation:
Slope intercept form: y =mx +c
5x - 2y = 10
-2y = -5x + 10

Step-by-step explanation:
Total balls = 12
Probability of 2 black balls = 2/ 8 = 1/4
Probability of 2 red balls = 2/4 = 1/2
Probability of both red and black = 2/12 = 1/6
