Write an equation of the line that passes the point and given slope (1, -1); m=3

(y+1) = 3(x-1)

Step-by-step explanation: The key here is point slope form. Whenever you are given questions with a given point (y1, x1) and slope m just use this form, (y-y1)=m(x-x1)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
