Write a linear equation representing the information shown in the table A y 25x 5 B y 52x 5 C y 52x 5 D y 25x 5 class=

Respuesta :

Answer: C

Step-by-step explanation:

There are many ways to find the linear equation that matches the table, but let's do it so that we find the slope and y-intercept.

Based on the first entry (0,-5), we know that the y-intercept is -5.

To find slope, we take any two points and plug them into this [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We'll use the first two points.

[tex]m=\frac{0-(-5)}{2-0} =\frac{5}{2}[/tex]

Now, we know the slope is [tex]\frac{5}{2}[/tex].

The only equation that has the same slope and y-intercept that we found is C.
