First find the slope of A.
Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7
For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A. Mathematically:
m1*m2=-1 and in this case the perpendicular line will have a slope of:
4m/7=-1
4m=-7
m=-7/4
So the slope of the line perpendicular to A is -7/4

Answer:
2.125
Step-by-step explanation:
This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!
