Answer:

C. $\frac{13}{2}$

Step-by-step explanation:

The formula to calculate slope is m= $\frac{y2-y1}{x2-x1}$

(-1, 9) is x1 and y1, (-3, -3) is x2 and y2 in this formula.

$\frac{-4 - 9}{-3 - -1}$ --- plug in values

$\frac{-13}{-2}$ --- simplify

$\frac{-13}{-2}$ = $\frac{13}{2}$

1. Thom has a scale model of his car. The

MariettaO [177]

$x =\frac{4}{3}inch$ is the size in wheels on the scale model .

Step-by-step explanation:

Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?

We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:

Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,

⇒ $\frac{1}{12} = \frac{x}{16}$ { x is size of wheel in scale model }
