Question

If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?

y − 2x = 3

-2y + 3x = 1

y + 3x = 2

y + 2x = 3

Answer 1

We can write the equation of a line as:
(y-b) = m (x-a)
where m = the slope of the line, and (a,b) is a point on the line.

Substitute your values of m, a, and b into the above equation
