Where does the graph of y=-3x-18 intersect x-axis

It intersects at -6 on the x-axis.

Step-by-step explanation:

Use Desmos.com for these sort of problems it really helps. I will show you the screenshot of how I got my answer from graphing the equation on Desmos. Where the line intersects at the x-axis that is considered the x-intercept.

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)
