Answer:


\large\boxed{b)\ y=(3)/(4)x-1}

Explanation:

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


y=mx+b

m - slope

b = y-intercpt → (0, b)

The formula of a slope:


m=(y_2-y_1)/(x_2-x_1)

We have the points (4, 2) and (0, -1) - y-intercept → b = -1.

(we see this already which equation. Only in b) y-intercept is b = -1).

Anyway, calculate the slope:


m=(-1-2)/(0-4)=(-3)/(-4)=(3)/(4)

Finally we have the equation:


y=(3)/(4)x-1
