What is the equation of the parabola? coordinate plane with a parabola facing down with vertex at 0 comma 5, the point 0 comma 3 and a horizontal line going through 0 comma 7

y = −one eighthx2 + 5
y = one eighthx2 + 5
y = one eighthx2 − 5
y = −one eighthx2 − 5

Step-by-step explanation:

question is not clear

y=x to the second power or y=ax to the second power + bc+c

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
