write two equation lines passing through (5,7)
Answers
Answer:
For x= 5 and y=7,
y–x=2 —(1)
2x–y=3 —(2)
The slope can be found using the formula :
y2 – y1
m = ______
x2 – x1
Where m is the slope and ( x1, y1), (x2, y2) are the two points on the line.
Substituting the two points from the problem gives:
m = 8 – 3
–2–1
m = 5
– 3
mp = – 1
m
Substituting gives: mp = _ 3 = 3
5 5
now that we have the slope of the perpendicular line and one point that we can use the point - slope formula to find the equation.The point - slope formula states: (y – y1) = (x – x1)
Where m is the slope and ( x1, y1) is a point the line passes through.
The point from the problem gives:
(y –7) = 3 (x – 5)
5
