Given a line passing through points (1, 0) and (4,9),
what is the slope of the line?

  3

Step-by-step explanation:

The slope (m) is the ratio of the difference in y-values to the corresponding difference in x-values:

  m = (y2 -y1)/(x2 -x1)

  m = (9 -0)/(4 -1) = 9/3

  m = 3

The slope of the line is 3.

hi, i am not sure about this one but i think its d,

hope this !

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
