The slope of the line that contains the points (1 -1) and (-2 8) is -3

Step-by-step explanation:

Slope measures the steepness of a line. It is the ratio of vertical change to horizontal change. If the line increasing, the slope is positive and if the line is decreasing the slope is negative. If the line is horizontal slope is zero and if the line is vertical slope is undefined.

Equation for slope = (y2-y1)/(x2-x1)

here y2= 8

x2=-2

y1=-1

x1=1

Substituting the following,

slope = (8+1)/(-2-1)

=9/-3

=-3

hence the slope is -3

Find the quotient. Simplify your answer.<br> 7y/6 divides by z/-2
HACTEHA [7]

Answer:

-7y/3z

Step-by-step explanation:

When dividing fractions, we flip the second one so that we can multiply the 2 fractions. When we do this, we get 7y/6 * -2/z. When we multiply the numerators and denominators, we get -14y/6z. Simplifying (dividing the numerator and denominator by 2), we get -7y/3z.

What’s the answer and work for this? Someone please telllllllll meeee!!!!
HACTEHA [7]

Answer: 25

Step-by-step explanation: The median is the average of the middle two numbers and if the median will be 17.5 then the sum of the middle numbers will be 35, and when we arrange the numbers in the least to greatest order we realize that 10 will be one of the middle two numbers when a number is added, and so the other number must be 25. Hope this helped!
