Which linear equation best represents the data given in the table?

kirill115 [55]

Linear equations are equations that have constant slopes

The linear equation that represents the table is (a) y = 7x +4

<h3>How to determine the linear equation</h3>

Start by calculating the slope (m) using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{-10 +17}{-2 +3}$

Simplify

$m = \frac{7}{1}$

$m = 7$

The equation is then calculated as:

$y = m(x -x_1) + y_1$

So, we have:

$y = 7(x +2) -10$

Open the brackets

$y = 7x +14 -10$

$y = 7x +4$

Hence, the linear equation that represents the table is (a) y = 7x +4

What the result of √[(-2a)^ 2]

Tanya [424]

If you take the square root of a number squared number then they cancel each other out and the number stays the same i.e. √[(4)^2] would equal 4.

In this problem the square root and numbered squared cancel out to leave the problem as -2a.

The solution of this problem is -2a
