Answer:
y = 5x - 7
Explanation:
the equation you want to find is in the form of y = mx + b
(y2 - y1) / (x2 - x1) is a formula to determine the slope of a line from two points
(3 - [-2]) / (2 - 1) = m (m meaning slope)
5 / 1 = m
5 = m
now that you know m, you can solve for b by inserting one of the points in the slope form equation and the slope
y = mx + b
3 = (5)(2) + b
3 = 10 + b
subtract 10 from both sides
-7 = b
the equation will be y = 5x - 7
