Aline has a slope of -1/4 and passes through point (-5/4,1) what is the equation of the line? a. y= -1/4x+ 21/16 b. y= -1/4x+11/16 c. y=-1/4x-1/4 d. y= -1/4x-5/4

The correct answer is B. y = -1/4x + 11/16

Step-by-step explanation:

In order to find this, we must plug in the slope and the point into point-slope form. We can then solve for slope intercept form.

y - y1 = m(x - x1)

y - 1 = -1/4(x - -5/4)

y - 1 = -1/4(x + 5/4)

y - 1 = -1/4x - 5/16

y = -1/4x + 11/16

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
