Question

: find the slope of 8 and 7. Write your answer in simples from!

Answer 1

7).

In the graph 7

The two coordinates are (-1,-1) and (1,3)

The slope of a line is expresses as :

`\begin{gathered} \text{Slope = }(y_2-y_1)/(x_2-x_1) \\ \text{Here x}_1=-1,x_2=1,y_1=-1,y_2=3 \\ \text{Slope = }(3-(-1))/(1-(-1)) \\ \text{Slope =}(3+1)/(1+1) \\ \text{Slope =}(4)/(2) \\ \text{Slope =2} \end{gathered}`

Answer slope of grap 7 is 2.

8)

In the graph 8

The coordinates are (-2,4) and (2,0)

The slope will express as :

`\begin{gathered} \text{Slope = }(y_2-y_1)/(x_2-x_1) \\ \text{Here x}_1=-2,x_2=2,y_1=4,y_2=0 \\ \text{Slope = }(0-4)/(2-(-2)) \\ \text{Slope =}(-4)/(2+2) \\ \text{Slope =}(-4)/(4) \\ \text{Slope =}-1 \end{gathered}`

Slope of graph 8 is (-1).

Answer :

(7) slope = 2

(8) slope = -1
