According to the table, what is the increase in monthly pay for each hour of training?

Option D is correct

$20 is the increase in monthly pay for each hour of training

Step-by-step explanation:

Using slope formula:

As per the statement:

Let x represents the Hours of training and y represents the Monthly pay.

From the given table:

Let any two points i.e,

(10, 1220) and (20, 1420)

Since, increase in monthly pay for each hour of training is represented by slope.

then;

⇒

Therefore, $20 is the increase in monthly pay for each hour of training

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
