Answer: Slope:4; y-intercept: (0,0)
Step-by-step explanation:
To find the slope:
1. Take two points, I'm going to take (3,12) and (2,8).
2. Put it into the slope equation: 
=> 
=> 4
Slope is 4!
Find the y intercept: Its already in the table for you.
(0,0)
Have a nice day! :D
Answer: I haven't been in Geometry in a while but watch this video. It should help you.

The answer is 5sqrt2 or 7.07
Since you have one 45 degree angle the other angle is also 45 degrees. This gives you a right isosceles triangle.
This can be solved using Pythagorean theorem or trig ratios.
a^2+a^2= 100
2a^2 = 100
a^2=50
a= sqrt 50
a=5sqrt2
So for something to be perpendicular the gradient must be the negative reciprocal of your original line so your original gradient is 2 so your new gradient will be -1/2. Then you have y = -1/2 x + c . Now you substitute this into the point (4,-1) to get -1 = -1/2 x 4 + c and -1/2 x 4 = -2 so you have -1 = -2 + c so c = 1 so then you put the equation together to get y = -1/2 x + 1
Hope this helps :))
