Question

Can Anyone solve this question??

Answer 1

Answer:

Explanation:

Given, linear equation is y=3

i)

If Y = 3 is treated as an equation in one

variable, then it has a unique solution y= 3. So it is a point on the number

line.

ii)

Given equation Y equal to 3 can be written as 0.x

+ y = 3, which is a linear equation in two variables x and y.

This is represented by a .Here all the values of

X are permissible because 0.x is always 0. However, y must satisfy the equation

y=3.

Thus, the graph AB is a line parallel to X-axis

at a distance of 3 units in the positive direction of Y axis.

Answer 2

The equation that we are given $\mathbf{(-at^2+bt+c)}}$ is a parabola and we are told to describe what happens when we change c (the y-intercept).

From what we know about functions and function translations, we know that changing the value of c will shift the entire parabola upwards or downwards, which will change not only the y-intercept (in this case called the “h intercept”), but also the maximum height of the parabola as well as its x-intercept (in this case called the t intercept). You can see this in action when we raise the value of the y-intercept of our parabola.

Options I, II, and III are all correct.
