Question

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.

Answer 1

Answer:

Step-by-step explanation:

hello :

Use the point-slope formula.

y - y_1 = m(x - x_1)    .... x_1 = 10    and  y_1 =9   or 35 , 0

 A(10,9)    B(35,0)

the slope is :  m=  (YB - YA)/(XB -XA)   (the slope)

m= (0-9)/(35-10) = -9/25

an equation is : y - 9 = -9/25(x - 10)
