Answer:

(y2 - y1)/(x2-x1)

Step-by-step explanation:

if you have 2 points (x1,x2) and (y1,y2), just plug it in the formula for slope m

m = (y2 - y1)/(x2-x1)

Which equation represents the graph?

frosja888 [35]

Answer:

The answer is A) y+4 =3(x+3)

Step-by-step explanation:

The slope is the rate of change, which you can see from the graph is m = 3/1 = 3.

Your options are given in point-slope form:

y-y1=m(x-x1)

Pick a point from the graph. I used;

(-3, -4). Now plug this into your point slope form equation.

y-(-4) = 3(x-(-3))

y+4=3(x+3)

The park and movie theater are 3.4 inches apart on a map. If the map has a scale of 0.25 inch = 5 miles, find the actual distanc

lianna [129]

The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.

Step-by-step explanation:

The given is,

Park and movie theater are 3.4 inches apart

Map has a scale of 0.25 inch = 5 miles

Step:1

Formula to calculate the number of scales for distance between park and theater,

$= \frac{Distance in map}{Scale value of map}$

$= \frac{3.4}{0.25}$

= 13.6

number of scales for distance between park and theater = 13.6

Step:2

Formula to convert distance inches to miles

$= Number of scale$ × $Equivalent value inches to miles$

= 13.6 × 5

= 68

Actual distance between park and theater = 68 miles

Result:

The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.
