A line has a slope of -2 and goes through the point (0, -5). What is the equation of this line, in slope-intercept form?

y=-2x-5

Step-by-step explanation:

For m=-2

For (0,-5) a=0 AND b=-5

(use the equation y-b=m(x-a) to find the equation of the line)

y-b=m(x-a)

(sub the values of m (the slope) and a&b (from the point passing through the line)

y - (-5) = (-2) × ( x - 0 )

(simplify)

y+5=-2(x-0)

(expand the bracket)

y+5 = -2x+0

(subtract 5 for both sides)

y=-2x+0-5

(simplify)

y=-2x-5
