The slope would be c, vertical line is 0

The answer would be d. This is because parallel lines have the same slope. Lets say the first line is f(x). The slope of this would be undefined because all the x-coordinates are the same, so if you tried to find the slope, you would use the slope formula, y^2-y^1/x^2-x^1 and if we used the points (1, 1) and (1,2) we would end up with 2-1/1-1 = 1/0. Because there is a zero in the denominator, it makes f(x) undefined. And as I said before, parallel lines have the same slope, f(x)' would also be undefined.

A plane flew 525 miles in 1.75 hours. Find the average speed of the plane.

ale4655 [162]

We are trying to find the average speed of the plane, which is mph, or $\dfrac{\textrm{miles}}{\textrm{hour}}$ . Using proportions, we can find the average speed of the plane in mph:

$\dfrac{525 \,\, \textrm{miles}}{1.75 \,\,\textrm{hours}} = \dfrac{x \,\, \textrm{miles}}{1 \,\,\textrm{hour}}$

Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that $x$ .

$\dfrac{525}{1.75} \,\textrm{miles} = x \,\textrm{miles}$

Multiply the entire equation by $1 \,\textrm{hour}$

$\dfrac{525}{1.75} = 300 = x$

Divide both sides of the equation by $1 \,\textrm{mile}$ to clear both sides of the mile unit

The average speed of the plane is 300 mph.
