A light shines from the top of a pole 5050 ft high. A ball is dropped from the same height from a point 2020 ft away from the light. How fast is the shadow of the ball moving along the ground one half 1 2 sec later? (Assume the ball falls a distance s equals 16 t squareds=16t2 in t sec.)

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

2x + 8

step-by-step explanation:

the answer is -1 for this question
