Question

Ryan owns a snow shoveling business. For each driveway, they charges $50 plus $70 per hour of work. A linear equation that expresses the total amount of money Ryan earns per driveway is y=70x+50. What are the independent and dependent variables? What is the y-intercept and the slope?

Answer 1

The x is the independent variable and y represents the dependent variable, the slope is 70, and the y-intercept is 50.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

We have a linear equation:

y = 70x + 50

That represents the charges of $50 plus $70 per hour of work.

Here x is the independent variable and y represents the dependent variable.

The standard form of a line:

y = mx + c

On comparing:

m = 70

c = 50

Thus, the x is the independent variable and y represents the dependent variable, the slope is 70, and the y-intercept is 50.
