Answer: y=5x+3
Step by step explanation:
Perpendicular meaning that the product of the slope/gradient is -1 hence ...
-1/5 * x = -1
x = -1/-1/5
x = 5
The equation perpendicular to y=-1/5x-3 is y=5x-c
Now it contains the points (1,2)
x variable is 1 and y variable is 2 plug them into the line equation
2=5(1)-c
2=5-c
2-5=-c
-3=-c divide by -1
3=c
Hence the perpendicular equation is y=5x+3
Hopefully it’s correct :)

If a child has blue eyes and both of her parents have brown eyes, what does this tell you about the allele for
nadezda [96]

Answer: Blue eyes are caused by a recessive allele.

Both parents had a recessive gene for blue eyes, but both parents also had a dominant gene for brown eyes. The two genes for blue eyes happened to meet each other and give the child blue eyes.

Also, put this in the biology section next time.
