Answer:
yes it gas a unique solution
Step-by-step explanation:
8x+3=8x+7
Recognize the differnce of 2 perfect sqares
recall that a²-b²=(a-b)(a+b)
so
169x²-64=
(13x)²-(8)²=
(13x-8)(13x+8)
To find a perpendicular line, the slope is opposite reciprocal. The slope would be -4x.
Put in point slope form:
y - 7 = -4(x - 2)
y - 7 = -4x + 8
y = -4x + 15
(line perpendicular to given equation and goes through the point)
Hope this helps!! :)
