Answer:
y = 
x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 
x - 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (9, - 2), thus
y - (- 2) = (x - 9), that is
y + 2 = (x - 9) ← in point- slope form
Distribute right side and rearrange
y + 2 = x - 6 ( subtract 2 from both sides )
y = x - 8 ← in slope- intercept form
The value of a and b in the product of 4+3i and its conjugate in the format a + bi are 25 and 0.
<h3>What is conjugate?</h3>
The conjugate is where we change the sign in the middle of two terms. For example:
3y + 1
conjugate of 3y + 1 is 3y - 1.
Therefore, the conjugate of 4 + 3i is 4 - 3i.
The product of 4 + 3i and its conjugate is as follows:
(4 + 3i)(4 - 3i) = 16 - 12i + 12i - 9(i)²
Therefore,
16 - 9i²
i² = -1
Hence,
16 - 9(-1) = 25
It can be written in the form a complex form → (25 + 0.i)
Therefore, a = 25 and b = 0.
