Answer: y=-x+1
Step-by-step explanation: So we know one equation of the line. And we know the slope of our soon to be line (the line that we're trying to find) So what you do is you graph it and then get your equation in slope intercept form. (I also noticed in your attached picture that the only problem you couldn't get had a negative slope, so incase you don't know it means it's not going from top to bottom, but from bottom to top(in simple terms))
