Answer:
y = -1
+ 1
Step-by-step explanation:
The line (a) passing through point (3, -4) is perpendicular to line (b) whose equation is; y = -2 + 
x
The slope of line (b) =
For perpendicular lines, the product of their slopes = -1
So line (a) has a slope of: -1 ÷ = -
Taking another point (x,y) on line (a);
Slope = change in y ÷ change in x
= -
y + 4 = (x - 3)
y = -x + 5 - 4
y = -x + 1
Finally,
y = -1 + 1
The probability that the train will be there when Alex arrives is 0.1.
Given that the time that train arrives between 1:00 P.M to 2:00 P.M. and waits for 10 minutes. Alex arrives between 1:00 P.M to 2:00 P.M.
We are required to find the probability that the train when Alex arrives.
Probability is the likeliness of happening an event among all the events that are possible to happen.
Probability=Number of items/total number of items.
Number of combinations of timings in which the train may have arrived=60/10=6 combinations
Number of ways in which Alex arrives at the station=60.
Probability=6/60
=1/10
=0.1
Hence the probability that the train will be there when Alex arrives ie 0.1.
Question is incomplete. The following things should be included:
Timing in which train arrives is between 1:00 P.M and 2:00 P.M.The train waits for 10 minutes. Alex arrives between 1:00 P.M and 2:00 P.M.

Answer:
5x - 6y = 14
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y - 1 = 
(x - 4)
Multiply through by 6 to eliminate the fraction
6y - 6 = 5(x - 4) ← distribute
6y - 6 = 5x - 20 ( add 20 to both sides )
6y + 14 = 5x ( subtract 6y from both sides )
14 = 5x - 6y , thus
5x - 6y = 14 ← in standard form
The answer to the squence is either d or a i believe
