What is the equation of the line, in point-slope form, that passes through the points (-1, 7) and (-2, 3)? a. y + 7 = -4(x - 1) b. y - 7 = -4(x + 1) c. y + 7 = 4(x - 1) d. y - 7 = 4(x + 1)

In general point-point form, the equation for the line through (a,b) and (c,d) is

Here we have (a,b)=(-1,7) and (c,d)=(-2,3)
