Step-by-step explanation:
Given the line y-1 = 1(x+2), in order to know the line that is perpendicular to the given line, we will first find the slope of the known line.
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the intercept
Rewrite the equation given
y-1 = 1(x+2)
y-1 = x+2
y = x+2+1
y = x+3
Comparing to the standard form, the slope m = 1.
For two lines to be perpendicular, the product of their slope must be -1 i.e mM = -1
Substitute
1(M) = -1
M = -1
For us to know the line that is perpendicular to the given line, its slope must be -1.
<em>Since none of the equation has a slope of -1, hence none of the lines are perpendicular to the line y - 1= 1(x+2).</em>

Answer:
b
Step-by-step explanation:
Answer:(2x + 9i)(2x - 9i)
Step-by-step explanation:
a^2 - b^2 = (a+b)(a-b)
a^2 + b^2 = (a+bi)(a-bi) = a^2 + abi - abi - b^2 i^2
But -b^2 i^2 = +b^2
