Answer:

y = 7

Step-by-step explanation:

The straight line which is perpendicular to the y-axis will be either x-axis or parallel to the x-axis.

Now, the general equation for all straight line which is either x-axis or parallel to x-axis are given by y = c ........... (1), where c is any constant.

For c = 0 the line will be x -axis. therefore, y = 0, is the equation of x-axis.

Now, if the line (1) passes through the point (-2, 7), then the equation will be y = 7. (Answer)  

{Since, the point (-2,7) will satisfy the equation (1) and then c will be equal to 7.}

The radius of the Earth is roughly twice the radius of the planet Mars. Raj claims that the volume of the Earth must therefore b
Volgvan
The claim is incorrect. Treating the planets as basic spheres, the formula of the volume of a sphere states that volume = (4/3)(pi*r^3), where r is the radius. Since r is raised to the power of three, then doubling the radius would result in a volume that is 8 times larger than the original.

Once a delay or disability is diagnosed, the best thing to do is to continue to be a family’s knowledgeable and reliable partner
meriva

Once you detect that there is a delay or disability, then you should continue to be the reliable partner in child care to the family so this is True.

<h3>What should be done when a delay in child development is seen?</h3>

The observation and screening process can lead to a child care partner discovering a delay or disability.

When this happens, you should report to your supervisor to check if the child is eligible for federal and state programs related to their condition. Whatever the case, you should remain accessible to the family as their partner in child care.
