Write the slope-intercept form equation of the line that passes through the points (1,6) and (4,15) .

Answer 1

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept (where x = 0).

Use the given points, substituted into the standard equation, to get 2 equation with m and b as unknowns. Solve this pair of equations for m and b, using the standard methods
