Question

What is the slope of the line shown ?

a) slope= - 1/2

b) slope= 7

c) slope= 2

d) slope= -2

Answer 1

-2

Step-by-step explanation:

rise/run

Answer 2

Step-by-step explanation:

Remember that the slope of a line is define by the change in y divided by the change in x. In other words:

`m=(Change \ in \ y)/(Change \ in \ x)`

We can calculate the slope of any line using two points, so:

`m=(y_(2)-y_(1))/(x_(2)-x_(1))`

From the graph, we know two points:

`(x_(1),y_(1))=(0.7) \\ \\ (x_(2),y_(2))=(3.5,0)`

Therefore, the slope is:

`m=(0-7)/(3.5-0)=-2`

Therefore, the correct option is:

d) slope= -2
