Answer:

slope is $-\frac{3}{4}$

Step-by-step explanation:

1,-1 -3,2 are two points on the graph

the equation to find slope is $\frac{y_{1}- y_{2} }{x_{1}- x_{2} }$

so $\frac{2--1}{-3-1} = -\frac{3}{4}$

or you can count how many places it changed in the equation $\frac{rise}{run}$

A map show a town with an area of 3.5 inches.If the map has a scale of 1 inch:4 miles,what is the actual area of the town?

cestrela7 [59]

Answer:

The actual area of the town is 14 miles.

Step-by-step explanation:

Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:

Scale: 1 inch:4 miles

map area: 3.5 inches

If the actual area is x, you can say that:

3.5:x=1:4

This would be:

$\frac{3.5}{x}=\frac{1}{4}$

Now, you can solve for x:

x=(3.5*4)/1

x=14

According to this, the answer is that the actual area of the town is 14 miles.
