Answer:
-6x + 7y = 11
Explanation:
The point-slope form of an equation of a line:

m - slope
The formula of a slope:

We have the points (-3, -1) and (1/2, 2). Substitute:

Convert to the standard form Ax + By = C:
multiply both sides by 7
use the distributive property
subtract 7 from both sides
subtract 6x from both sides
