Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
Answer:
Step-by-step explanation:
The point of intersection of

and
is the solution of the two equations.
We add equation (1) and equation(2) to get,



We put
into equation (1) to get,




Therefore the line passes through the point,
.
The line also passes through the point of intersection of

and

We subtract equation (3) from equation (4) to obtain,



We substitute this value into equation (4) to get,





The line also passes through

The slope of the line is

The equation of the line is


is the required equation

Answer:
68 4/7 miles/hour
Step-by-step explanation:
The unit rate is found by dividing miles by hours:
(120 miles)/(7/4 hours) = 480/7 miles/hour = 68 4/7 miles/hour
An upper extreme is the highest number on the number line give. So the Upper extreme is 11
Answer:
Option (4)
Step-by-step explanation:
Point A is located at (0, 4) and point C is located at (-3, 5).
Let the point B is located at
the distance from A and C.
In other words ratio of the segments AB and BC = m : n = 1 : 3
Coordinates of a point (x, y) which divides a segment having ends
and
= 
If the ends of the segment are (0, 4) and (-3, 5), coordinates of point B will be
= 
= 
= (-1, 7)
Option (4) will be the answer.
