Answer:
1
Step-by-step explanation:
To know the slope of a line we have the next expression:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
By the figure we have the next two points (-4,2) and (3,9) then:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-2}{3-(-4)}=\dfrac{7}{3+4}=\dfrac{7}{7}=1[/tex]
THen the slope is equal to 1.
