2x + y = 1
3x - y = -6
---------------add
5x = -5
x = -5/5
x = -1
2(-1) + y = 1
-2 + y = 1
y = 1 + 2
y = 3
solution is (-1,3)
Answer: 1)The drivers with low alcohol in take from the breathlyser, being above the limit, A = 5/100;
2)The drivers above the alcohol limit, give reading below that level, B = 15/100;
3) The drivers above the alcohol limit that are arrested at radom by police, C = 12/100
Step-by-step explanation: a) A + B + C = 5/100 + 15/100 + 12/100 = 32/100
b) 1 - ( A + B + C) = 1 - 32/100 = 68/100
c) A = 5/100
d) 1 - 5/100 = 95/100

Answer:
The slope of a line that includes the points (4, -2) and (5, 0) is 2
Step-by-step explanation:
You know that the formula y - y1 = m(x - x1) is the point-slope form of the equation of a line where m is the slope of a line.
The line must include the points (4, -2) and (5, 0). So, being:
- (x,y)= (4,-2)
- (x1,y1)= (5, 0)
and replacing in the point-slope form of the equation of a line:
-2-0=m(4-5)
You solve the equation for m and get:
-2=m*(-1)

m=2
<u><em>The slope of a line that includes the points (4, -2) and (5, 0) is 2</em></u>
