Question

Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordinates.

slope: −1−1, ordered pair: (−1,−3)

Answer 1

slope =-1 means the coefficient of the x term is -1, when the equation is solved for y

y=-x+b b= y intercept. solve for b by plugging in the point (-1,-3)

-3=-(-1)=b = 1+b

b=-4

y=-x-4
