Answer:

D.
\boxed{5y-4x=5}

Explanation:

Slope = m = 4/5

y - intercept = b = 1 (As from the point (0,1) , y-intercept is when x = 0)

So, the equation becomes

=>
y = mx+b

=>
y = (4)/(5) x +1

=>
y - (4)/(5) x = 1

Multiplying both sides by 5

=>
5y-4x = 5

Answer:

The answer is option D.

Explanation:

Equation of the line using point (0, 1) and slope 4/5 is


y - 1 = (4)/(5) (x - 0) \\ \\ 5y - 5 = 4x \\ \\ 5y - 4x = 5

Hope this helps you
