Question

Find the equation of a line that passes through the point (0,4) and has a gradient of -2

Answer 1

y = - 2x + 4

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 2 and c = 4 ( crosses y- axis at (0, 4 ) ) , then

y = - 2x + 4 ← equation of line
