Which of the value of x satisfies the equation below -2x-7=12

1 answer:

8 0

Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

How to find the slope from a table of data

sammy [17]

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is $\frac{dy}{dx}$ or:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

$\frac{2 - 1}{2 - 1}$
