Answer: 2
Step-by-step explanation:The slope of a line is the ratio of the change in y-values to the change in x-values between two points on the line.
To find the slope, we first need to find two points on the line, for example (4,12) and (7,18).
Then, the slope can be calculated as:
(18 - 12) / (7 - 4) = 6 / 3 = 2.
The slope is 2.
