what is the equation in point-slope form of the line that passes through the point ( -1,,-4) has a slop of a -3

Vesnalui [34]

The answer has to resemble y=Mx+b so to find your y intercept plug in your coordinates into that equation so put your slope in for m and your x intercept in for x and the y intercept in for y so -4= -3(-1)+b now get b alone -1=b so your equation would be y=-3x-1
