Answer:
Slope of a line equation.
Formula for slope of line n is m= rise/run. y2-y1/x2-x1
(7,6) is (x1, y1) and (5,13) is (x2,y2). Simply plug these values in to the equation and solve.
Explanation:
(13)-(6) = 7.
(5)-(7) = -2.
7/-2 = - 7/2
- 7/2 = -3.5.
Perpendicular just means that the 1. answer changes sign (pos/neg). This answer is negative, so it becomes a positive. 2. the denominator number switches places with the numerator number. so 7/2 becomes 2/7. Decimal version is 3.5/1 becomes 1/3.5
Final Answer: 1/3.5 or 2/7
