Question

find the slope of line passing through the points 4 ,- 3 and 6 ,- 3​

Answer 1

Answer:

slope= 0 Ans

Explanation:

m= y2-y1÷X2-X1

= -3-(-3)÷6+4

= 0÷10= 0

Answer 2

Chapter name :

STRAIGHT LINES

Solution :

(i) Let

be tha given points. Then, slope of AB=

<br> (ii) Let C(4,-3) and D(6,-3) be the given points. Then, slope of CD=

<br> ALTER: <br> The points C(4,-3) and D(6,-3) have the same y-coordinate. So, CD is a line parallel to the line x-axis. Hence, it slope is 0. <br> (iii) Let P(3,-1) and Q(3,2) , which is not defined. Slope of PQ=

which is not defined <br> ALTER: <br> The points P(3,-1) and Q(3,2) have the same x-coordinates. So, PQ is a vertical line. Hence, its slope is not defined.
