Question

If a line with a slope of 4 crosses the y-axis at (0, 1), what is the equation of the line?

y − 4x = 1

y + 4x = 1

x − 4y = 1

x + 4y = 1

Answer 2

you will have to use the point slope formula : y - y1 = m(x - x1)
set 1 (0,1).....where x1 = 0 and y1 = 1
slope (m) = 4
now sub your info into the formula...
y - y1 = m(x - x1)
y - 1 = 4(x - 0) (distribute through the parenthesis)
y - 1 = 4x - 0
y - 4x = 1 <-- answer....its the first one
