So We Have:

11i(5 + 8i)

We Need To Distribute.

We Get:

55 + 88i²

I think it's 81, but not quite sure.

When the **coordinates** are (10,6) and (20,9) and the **slope** is 3/10, the linear **equation** is 3x-10y=-30.

<h3>What is linear equation?</h3>

A linear **equation** is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "**linear** equation of two variables." If an equation has the formula y=mx+b, with m representing the slope and b the y-**intercept**, it is said to be linear. Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Here,

The given **points**=(10,6) and (20,9)

x1=10

y1=6

m=(y2-y1)/(x2-x1)

=(9-6)(20-10)

m=3/10

(y-y1)=m(x-x1)

y-6=3/10(x-10)

10(y-6)=3(x-10)

10y-60=3x-30

3x-10y=-30

The linear **equation** is 3x-10y=-30 when **coordinates** are (10,6) and (20,9) and the **slope** is 3/10.
