Choose the equation below that represents the line that passes through the point (-2, -1) and has a slope of 5.

y - 1 = 5(x - 2)
y + 1 = 5(x + 2)
y + 2 = 5(x + 1)
y - 2 = 5(x - 1)

Choose the equation below that represents the line that passes through the point (-2, -1) and has a slope of 5.
 	
	y - 1 = 5(x - 2)
	y + 1 = 5(x + 2)
	y + 2 = 5(x + 1)
	y - 2 = 5(x - 1)

anonymous · Answer

The formula we'll be using is:
$$y-y_1=m(x-x_1)$$where m is the slope of the line, and x_1,y_1 are the coordinates of any point on the line. You have the slope and a point, so you have everything you need to plug in.
