Can you solve and do step by step?

[quasi goblet]

so the formula for the slope of a line passing through 2 given points is delta y / delta x

giving you 2-1/4--3 = 1/7

so the equation of the line so far is y = 1/7x + b

fill in a point (lets say (4,2))

the 4 is the x and the 2 is the y

so 2 = 1/7 times 4 + b

2= 4/7 + b

10/7 = b
