Y=4 and x=1 . You have to set the second equation to where x is by itself on one side which would be x=2y-7 then you plug the 2y-7 in for x in the top equation and solve for y. Once you get y you plug that number in for x in the second equation
Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical - as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan.
