What is the rate of change of the linear relationship modeled in the table (-2,5) (-1,4) (0,3) (1,2)
poizon [28]

The rate of change of the linear relationship is -1.

Explanation:

It is given that there is a linear relationship between all these points, these points lie on a straight line.

The equation to find the slope passing through two points \left(x_{1}, y_{1}\right) and \left(x_{2}, y_{2}\right) is given by

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the points (-2,5) and (-1,4), we get,

\begin{aligned}m &=\frac{4-5}{-1+2} \\&=\frac{-1}{1} \\&=-1\end{aligned}

Thus, the slope is -1.

Thus, the rate of change of the linear relationship is -1.

I need help I don’t understand
lara [203]

you'll first need to understand the symbols, I've attched a cheat sheet :)

you'll need to see if AB is linked to CD reversed.

If not then it's not A

For B you'll have to see if the angles are parralel to each other.

and for C you'll have to see if the angles are the same.

and D is the same as C

so the answer is ab=cd

<h2>now you understand :)</h2>
