I think -8 -64 but srry if wrong
        
             
        
        
        
For the case of a line through 
(
2
,
7
)
 and 
(
1
,
−
4
)
 we have
slope 
m
=
Δ
y
Δ
x
=
−
4
−
7
1
−
2
=
−
11
−
1
=
11
Using the point 
(
2
,
7
)
 we can write the equation of the line in point slope form as:
y
−
7
=
m
(
x
−
2
)
 where the slope 
m
=
11
.
That is:
y
−
7
=
11
(
x
−
2
)
To get point intercept form, first expand the right hand side so...
y
−
7
=
11
x
−
(
11
⋅
2
)
=
11
x
−
22
Then add 
7
 to both sides to get:
y
=
11
x
−
15
=
11
x
+
(
−
15
)
This is point intercept ( 
y
=
m
x
+
c
 ) form with slope 
m
=
11
 and intercept 
c
=
−
15
.
 
        
             
        
        
        
Answer:
x=-1
Step-by-step explanation:
 
        
                    
             
        
        
        
Answer:
The average acceleration of the car will be 10 m/s.
Step-by-step explanation:
70 / 7 = 10 m/s. 
 
        
             
        
        
        
With the formula: m=(y1-y2)/(x1-x2) you can sub in the values to get the slope (m).
m=(4-2)/(2-(-3))
   = 2/5
Therefore the slope is 2/5.
