Answer: y^4 + \frac{-73}{35}y^2- 2

Step-by-step explanation:

Use FOIL:

y^4 + \frac{-14}{5}y^2 + \frac{5}{7}y^2 + \frac{-70}{35}

Make  \frac{-14}{5}y^2 and \frac{5}{7}y^2 have the same numerator:

\frac{-14*7}{5*7}y^2 =\frac{-98}{35}y^2

\frac{5*5}{7*5} y^2=\frac{25}{35} y^2

Then add like terms and simplify:

y^4 + \frac{-98}{35}y^2 + \frac{25}{35} y^2 + \frac{-70}{35}

y^4 + \frac{-73}{35}y^2- 2

(3,1) m=0<br> In standard form
diamong [38]

0x + y = 1 is the standard form of (3, 1) with m = 0

<u>Solution:</u>

We have been given a point and slope of an equation and have been asked to write it in the standard form.

The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.

The given point is (3,1) and the slope is 0

To write in standard form we will first write it in point slope form and then rearrange it into a standard from.

The point slope form of line is given as:

y-y_{1}=m\left(x-x_{1}\right)

Where "m" is the slope of the line

Here in this problem, m = 0 , x_1 = 3 and y_1 = 1

y - 1 = 0(x - 3)

y - 1 = 0

y = 1

since the above equation doesn’t have an ‘x’ term we convert into a standard form as follows:

0x + y = 1

This is the standard form for the given point and slope of a line.
