Use the graph to solve the system of linear equations. x+y=5
y-2x = - 4
4
2.
4
The solution is (0.0).

There is no graph

Step-by-step explanation:

One has to solve this using either substitution or elimination then...

x + y = 5

–2x + y = –4

x + y = 5

2x –y = 4

3x = 9

x = 3

y = 2

Solution (3 , 2)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
