The main cable of a suspension bridge forms a parabola, described by the equation y = a(x â’ h)2 k. Y =height in feet of the cable above the roadway x =horizontal distance in feet from the left bridge support a =a constant (h, k) =vertex of the parbola What is the vertex of the parbola? ( , ).

d. vertex

step-by-step explanation:

the answer is 31.27mph

i need points

step-by-step explanation:

sorry bubs

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
