The slope of this line is 2/3. what does that represent?

Slope of a line represents the money billed per lesson length.

Step-by-step explanation:

Slope of a line defined as the the number that measures the steepness and it is usually denoted by m.

It is also states the gradient of a line or the change in variable of y to the change in variable of x.

As per the statement:

Slope of a line is 2/3.

Here x axis represents the lesson length in minute and y axis represents the money billed in dollars

Then;

Slope of a line represents the money billed per lesson length.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
