The slope of a linear function can be obtained as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1,y1) and (x2,y2) are points of the line.
For this problem we just have to pick 2 points from the table (they don't have to be consecutive). I'll pick:
• x1 = 0
,
• y1 = 4
,
• x2 = 2
,
• y2 = 14
And now we compute the slope:
[tex]m=\frac{14-4}{2-0}=\frac{10}{2}=5[/tex]
The slope is 5 (third option)
