Test # Let x represent the figure number and represent the number of tiles in a Tile Pattern.
The equation y = 5x + 3 can be us to mode the Tile Pattern.
Explain the meaning of the 5 and the 3 in the equation.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

don't report but were is the digram

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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
