Line mn passes through points m(4, 3) and n(7, 12). if the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b?
–15
–9
3
9

To determine the value of b, we can use the two point form of an equation of a line since we are given to points. It is expressed as:

y - y1 = (y2-y1)/(x2-x1)(x -x1)
y - 3 = (12 - 3)/(7-4) (x - 4)
y -3 = 3 (x -4)
y = 3x - 9 

Therefore, the value of b is -9.

To determine the value of b, we can use the two point form of an equation of a line since we are given to points. It is expressed as:

y - y1 = (y2-y1)/(x2-x1)(x -x1)
y - 3 = (12 - 3)/(7-4) (x - 4)
y -3 = 3 (x -4)
y = 3x - 9 

Therefore, the value of b is -9.
