Question

Answer quick!!

What is the equation of the line that passes through the points (−2, 1) and (1, 10)?

3x − y = −7

3x − y = −5

3x − y = 5

x + 3y = −5

Answer 1

The answer is 3x - y = -7 (if you put both sets of coordinates in the place of x and y you get -7)
For example: 3•(-2) - 1 = -7
