Slope is 2, and (5, 3) is on the line.

3 = 2(5) + b

Step-by-step explanation:

Equation for a slope is y=mx+b.

Y = Y-value on the graph

M = The slope

X = X-value on the graph

B = Y-intercept

If the coordinates are ( x, y )

Then that must mean that x = 5 and y = 3 because the numbers would replace the variables in the same order

The B-value is unknown for now but you are able to find it by solving this algebraically.

3=2(5) + b

3 = 10 + b

-10 = -10 + b

-7 = b    

Because the 10 and the -10 would cancel each other. Leaving you with only -10 on the other side.

I hope that this helps.

too hard the other guy did it

step-by-step explanation:

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
