Line mn passes through points m4, 3) and m7, 12). if the equation of the line is written in slope-intercept form, y-mx+ b, what is the value of b?

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

The formula of a slope:

We have the points M(4, 3) and N(7, 12). Substitute:

Therefore we have the equation:

Put the coordinates of the point M to the equation:

           subtract 12 from both sides
